Ryker front tire size is Proprietary! Thanks again BRP........

I've been trying to find a source of automotive tires for the Ryker. BRP specifications for the front tire size is 145/60R/16. This tire is not to be found in the automotive world as far as I've been able to ascertain. Look here at a tire size table to confirm it yourself. https://www.tyresizecalculator.com/charts/tire-size-chart-metric-by-rim-wheel-diameter

Current standard automotive tires can be purchase in 145/80R/16 and 145/90R/16. The problem is the middle set of numbers which represent the aspect ratio of the tire, ie. the height of the sidewall. Standard auto tires will be too tall to fit within the fenders and also completely change the handling. The Nanny is not going to be happy either.

The rear tire size 205/45R/16 is not going to be a problem as automotive tires are available. This fact is heart warming since the rear tire is going to go away as smoke quit soon for some riders.

I guess the moral of the story is BRP plans on have us purchasing Ryker front tires only from the BRP dealers. That matches up well with the fact you need a huge 3ft. long torque wrench and a special socket to mount the wheels.

It looks like the Ryker has more that one shaft associated with it. Thanks again BRP........

I certainly see your point. It is extremely frustrating but I believe it will be less frustrating than my ST when it comes to normal maintenance and service.

This is what I will be looking at when tires are needed for my Ryker. Sometimes you just have to get outside the box!

I looooooooooooooooooooooove the " Vredestein Quatrac 5 " , it has the best performance rating of any tire that will fit the Spyder's ….. The smallest front tire they have ( info from the company )is a 185/50- 16 ……...However they make about 10 sizes that will fit the rear :clap::clap: ……. go the Vredestein Co. tire site to find accurate info ……. Mike …..PS, if the choice is either mediocre tires or space out the wheels - - I would space out the wheels.

Those tires are 30mm wider than the stock tires. Do you think they will fit in the fenders?

 

[ARtraveler]

It seems to be SOP with BRP. Lots of smart people here...and they will get the subject figured out quickly. :yes:

I came here for this comment. Thank you for your "Spydy-sense".

Can someone who actually has a Ryker nearby to look at please post up a pic of the size & load rating info printed on the sidewall, ie the 145/60R16 75V or whatever is there - or at least copy it into a post so that those of us who don't yet have access to them can see all the important tire info?? :dontknow:

You can get a lot of info from the printed stuff on the tire, and for that matter, if anyone can find the size & bead type stamp that should be somewhere on the rim as well, that might help a lot too!! It will probably be something like 5.5Jx16H2 ET32 or it might just be a portion of that, but there should be something on the rim. The bad news is that it MIGHT be printed in the well near the valve hole on the INSIDE of the rim, ie, you'd hafta take the tire off to read it?!? :gaah:

Is this what you are looking for? It is from the right front tire.

 

[GoandChase]

I also found this on the tire: 145/ 60r16 m/c

edit: found this on their website: MC145/60R16 66T front and MC205/45R16 77T rear.

Kenda tires for ever and ever and ever:

I found the data below on this thread: https://www.spyderlovers.com/forums...ires-vs-Spyder-(Kenda)&highlight=ryker+manual

Default Ryker Tires vs Spyder (Kenda)

Good morning, curious to see what Spyder owners know from past experience of the Kenda tire experience. I have not been keeping up but I know the "stock Kenda tires support only" policy with Spyders, at one time was/was not enforced? Is it still currently same scenario? I will see if my dealer can give prices yet on stock oem tire replacement.

I looked at manual, googled the tire sizes, not a lot of options.

Front:
Ryker 600 Ryker 900
Kenda KR390 145/60R16
M/C 66T

Ryker
900 Rally
Edition
Kenda KR392 145/60R16
M/C 66T

Rear:
Ryker 600 Ryker 900
Kenda KR391 205/45R16
M/C 77T

Ryker 900 Rally Edition
Kenda KR393 205/55R15
M/C 81T

I found this forward facing photo of a Ryker. From this distance it looks like the tire Ron has in mind may fit within the fenders. It would only add 1/2 inch on each side to the current tires and the aspect ratio would be okay too.

Nice find Ron!

Perhaps Ron can measure the fender clearance on his new Ryker and give us an update?

 

[Peter Aawen]

Thanks guys. That info (including the rim & load/pressure info) is what I was after.

The 'J' on the rim means that the Ryker rims are STILL automotive rims with automotive beads, (ie Car rims & beads, just like the Spyder rims) and not actually Motorcycle rims or beads. I'm a little intrigued with the 'MC' they've got in the size detail, but I suspect they've done the same 'hope this fools some of you' thing as they did with the Spyders & it's actually a made up 'special motorcycle only' label. I guess I'll hafta wait until I can get one of them in my hands to disect & see what they've actually done tho...... :dontknow:

Still, I reckon that we'll find there's a reasonable selection of 'J' type beaded tires out there for small/medium sports & performance vehicles that will have the same or better load & speed ratings, that are very likely constructed just a wee tad stronger than the OE stuff, and that will last longer while providing better ride, handling, grip, durability, and even more importantly, safety.... altho they may well be wearing slightly different 'nominal' sizes on the sidewalls. Just check the ACTUAL width & rolling diameter before committing your hard earned $$! And as we've found with the Spyders already, the Nanny really wont mind all that much just so long as you keep any changes reasonably close to the same variation between the front tires & the rear tire. :thumbup:

Try using this tire size calculator.

Plug the Rykers tire size in on the left and the list on the right will show you the compatible sizes.

Thanks Markububis, that is a great tire calculator.

It has a neat feature that allows you to compare two sizes of tires for comparison. I compared the Ryker front tire size 145/60R/16 and the Yokohama 175/50R/16. The diameter is very nearly exact, but the rub is the Yokohama is 1.2 inches wider. It may fit, perhaps Ron or someone else can take a ruler out to their Ryker and check it out for us.

 

[Peter Aawen]

Just be a bit wary of those tire size comparison tools, they generally only work on the tires nominal sizes, ie, that printed on the sidewall; and those sizes can be somewhat different to the tires ACTUAL physical size!! Frequently by as much as 20mm or so (in diameter &/or width) but there are a few examples out there where the variation is closer to 50mm/2" different!! :shocked:

Tire manufacturers use a variety of different methods to determine what nominal size they put on their tires, frequently even on different versions of their own tires too!! Some use the carcass diameter BEFORE the tread layers are formed & applied; while others use the completed tire INCLUDING the tread layers; &/or any combination of those & a bunch of other variations on the theme. So you really need to use the ACTUAL physical dimensions of the different tires; but those comparison tools help make a start! :thumbup:

 

[Sarge707]

On the Unique Ryker I will be using OEM replacement tires because they are designed for the attributes of the Special vehicle. As long as front and back get at least 15,000 miles I will use them. They should get better mileage because of the lighter weight- As long as your Not burning up the rear every stoplight.

 

[Hypurone]

Corrected in my post below....

 

[Leland]

There are 145/65-16's out there.... A tad taller, same section width. But no more of a difference than some of the non-Kenda tires some of us are using on our Spyders....

@hyperone

Thanks for the suggestion. I looked on the internet for 145/65R/16 and found none. I did find some 145/65R/15 in Europe.

Perhaps you can point me to the 145/65R/16 please? When BRP made the decision to use 16 inch wheels they really locked us into Kenda tires unlike anything Spyder owners can imagine.

It's going to be much harder to fix a automotive tires to the front of a Ryker anyway you look at it.

I think potential buyers should be aware of this fact.

I also think that the decision to use a single aluminum alloy wheel retaining nut is a terrible idea. It's going to create unnecessary complications for owners in the future. If BRP had stuck with normal steel lugnuts it would be far easier to service. They are making a big sales push by saying how easy it is to maintain a Ryker, Okay well what's up with an 65 mm aluminum nut on a steel spindle. That is going to corrode and the nut is going to get damaged with impact tool usage by some unknowing user. Top it off with the fact that 225 ft/lbs of torque is required to install and uninstall the nut. This is stupid!

I’m with you on this I’ll stick with Oem tires
