There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Are you happy with your aftermarket CAR tires?

Hello Sarah,
I left you a Private Message. Sometimes we don't notice them and I didn't want you to miss it.

No clearance issues on my 2019 F3S. I have not tried the Vredestein's (currently on my F3S wheels) on my 2022 RT since I shimmed the fenders. I was happy enough with the tire improvement of the Achilles 165/55R15's to use them on the RT. Shimming was done for future possibilities
OK, I see it was my bad for not reading your clear statements more carefully. The 2020+ RT's do have less room under the fender. We've had issues with the 175's on those. We now try to talk these customers out of mounting the 175's on the 2020+ RT's because of this. But we've not had any issues with the 165's so far. Probably a combination of manufacturing variance in the tire and fender configuration.
Thank you for setting me straight! I need that from time to time. All the time according to my wife!

Tire Rack.com now has 225/60-15 & 215/60-15 @ $122 & $118 per tire they ship for free ( don't answer any questions about what veh they are going on ....JUST DECLINE ) ..... Or the Riken Raptor 231/60-15 @ $ 82.00 ( I switched the the Raptor 8000mi.ago and love it ......Good luck .... Mike:thumbup:
While some 195/55R15 tires will physically 'fit' on the rear of your Spyder, they really are too narrow for the rim &/or for comfortable, safe riding! :lecturef_smilie:
I have fitted & ridden on a couple of tires in those nominal sizes just to see if they'd actually 'work' back there, and they did physically go on (with a little stretching & effort!
) and the Spyder wasn't completely impossible &/or dangerous to ride as a result; but seriously, I really STRONGLY wouldn't recommend fitting a rear tire in that size on a Spyder as anything but an 'Emergency just to get me home' sorta thing!! nojokeGenerally, for any Spyder model, I'd suggest that you don't want to go any smaller than a 205/50R15 or any larger than a 225/60R15, but pretty much any of the 50 thru to 65 profiles in sizes between those two extremes will work fairly well. The OEM tires are a bit on the 'small' side of their nominal size, so with one of them fitted, your speedo might read anything up to about 5-7ish mph faster than you're actually going (and your trip/odometer might be similarly optimistic too!
) so a slightly taller profile tire is likely to make your speedo (& trip/odo) closer to 'accurate'; while the VSS is designed & cailbrated to function well with any tires sized within that range; and there's physically room to fit most tires with those nominal sizes both onto the rim and into the wheel well, altho wider/taller tires will have less tolerance/room for suspension compression under load or thru use, so they might touch the inner fender/seat under-tray if you hit any sudden bumps/carry a heavy load... 
So on the rear of your Spyder, you can readily go for either a 205, a 215, or a 225 wide tire in a 50, 55, or 60 profile without any concerns, maybe even a 65 profile in either of the 2 narrower widths; but pretty much whatever way you look at it, a tire that's only 195 mm wide in any profile is not a going to be a good width for running on the rear of your Spyder! :lecturef_smilie:
Just Sayin' :cheers:
Ps: IIRC, I'm currently running a 205/65R15 M&S tire on the rear of my 2013 RT, but then, it's just not easy for us to get Altimax or Quatracs here in Oz.

Do you want the 205/60R 15? We can get you either one. Tire Rack should have them too. But don't tell them you're putting it on the back of a Spyder. They probably won't sell it to you if you do.
But if you're going to go with the Altimax RT45, that one comes in a 215/60R 15, which I would recommend. I wish the Vredestein would come in that size. But you have to go down to a 205 for that one.

BlueKnight, you may have said it already and shame on me if I missed it, but are you running the Raptors all around? Also, is 231/60-15 a type-o? I don't see that on tirerack.
I think I want to give them a try based on your many tire comments and reviews.

What a crock! What I do agree with is: The changes in handling are FAR IMPROVED over the OEM rubber bands when running car tires.

The Raptor only comes in REAR tire sizes .... I use the 215/60-15 size ...... And Yes, that 231/60-15 is a typo :dontknow: :banghead: ....Sorry ....Th e Raptor is only slightly lower rated than the Altimax ..... but is $50.00 cheaper and that is a Serious bargain ..... Mike :thumbup:

Ten or more years ago, I would have understood BRP's viewpoint. Stability control systems were a new fangled idea and manufacturers had little experience of how such systems behaved in the real world on anything other than the OEM tire fitments.
However, now most cars have stability control systems and we see the same cars fitted with differing tire brands as OEM provisions, depending upon the model year or even the batch they were produced in. I think a car manufacturer would have a hard time insisting on OEM provided tire brands as long as the tire fitted was of the correct size, loading and rating and from a name brand manufacturer. OK, I think there would exceptions for specialist very high performance cars, but often the OEM brand of tire in the correct fitment is not available after a few years of ownership for many vehicles. Telling twenty year old Rolls Royce or Bentley owners they can no longer drive their cars when the OEM fitment tires wear out, just plain silly.
Even modern two wheeled motorcycles are fitted with complex stability control driven ABS systems yet I don't hear the manufacturers stating that only one particular tire is approved fitment for the machine. Their own race teams choose different vendors or use the spec tire for the series. I've had various factory dealers over the years suggest and fit different tire brands over the generally cheaper and less performant OEM fitments.
Imagine, going to Costco to fit Michelin tires to your recent Toyota Camry and being told no, cannot do that as it came with some other brand as original fitment.
I think after this length of time BRP could have evaluated a few different tire brands and fitments to provide as an alternate to the OEM Kendas, especially considering the supply chain issues they often have in obtaining them.
Personally, I actually like the Kendas I have fitted to my Spyder. I find them a good compromise between handling and ride, albeit at the expense of longevity. I know I'm in the minority and it might not be a popular point of view, but there, that's just my personal opinion. However, not having an approved list of alternatives, unlike nearly every car and motorcycle manufacturer in existence, shows a bit of lack of maturity from BRP. Even their own dealers fit alternative vendors to their off road vehicles.
In fact, by minor changes to the OEM tire and wheel sizes, they could easily have an approved list of modern light car tires that with the right recommended pressures serve admirably on our vehicles. Even a minor change to 17" wheel sizes would open up a wide range of tires from major quality manufacturers and yet not change the geometry of the Spyder by any significant amount. Look at cars, they often come with a wide range of wheel and tire sizes and nobody says they are inherently dangerous.
BRP needs to get with the program, forcing its customers to have a single brand choice from a relatively small and obscure supplier, in the US, is patently one of reducing customer choice. If the whole stability control issue was really that sensitive, why not make the brake calipers and rotors a special size to stop people fitting Brembo or EBC parts, which are just a likely to affect the stability control system.
The whole thing has got to a point of nonsense and seriously underestimating the common sense intelligence of their customers when reading their proclamations on tire fitment choices.

The BRP story line is that you must use OEM Kenda tires because the computers on the Spyders recognize them :roflblack: ... However, BRP has Changed the tire tread and compounds of the OEM Kenda's three times to date, and they haven't recalled any Spyders to have the Computers RE-PROGRAMMED. Which makes their story line ..... Pure Hooey .... Mike :thumbup:

These days, with the level of cross communication available, it's more difficult to lie to the customer and get away with it. But there will always be those who remain loyal to the manufacturer regardless of the facts. Everyone gets to choose. And that's the way it should be.

Rear Riken Raptor installed.
Thanks for the recommendation
Thanks for this info ...... Please keep the Forum informed about your opinion of this tire ..... It's much less expensive to any of the other top performance tires ...IMHO & others .....Mike :thumbup:
