• 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.

RT-S Rear Tire

OK, let me get this straight. It IS OK to run the rear tire (Altimax T43) at 20 PSI? I just pulled my head out and checked. I'm at 24K miles on the Altimax and it's about to be ryding season. So replacement is imminent. Better early than late I suppose. My concern, and it has been mentioned in this thread, is about speed with various tires. I do not want to get a ticket and don't want to have to worry that I'm exceeding that 'allowed' max speed by even one of those mile things, oh yeah, MPH. I have a couple of 5 K mile trips planned this ryding season.

And, where is instruction on how to acquire, fill and post those travel maps of the US and Canada? I went a whole lot of new places last year.
 
TIRES

Has anybody tried Falken or Pirelli tires? Would you use a Touring tire vs. a Summer performance tire?
I've done quite a bit of research on Auto tires as they relate to our Spyders ..... here are some of my conclusions .... The Nanny ( ie. the VSS computer ) plays a large factor in determining at what point you stop gaining a traction advantage by using super sticky tires. I believe auto tires, any auto tires are much better than either the Kenda's or Arachnid's ..... On a three wheeled vehicle, the traction of the rear tire is more important than the fronts. Especially it's wet road traction. I discovered using super sticky tires,( front and rear ).... although they allow you to hold a turn much better/ faster..... they will cause the Nanny to trigger sooner and this interruption can / will effect the handling ( your turn line ). This usually slows you down more than if you went slower and didn't trigger the Nanny to begin with..... To comment on your Questions, I don't think the Falken's have great traction properties. I plan to put a Pirelli Four Season PLUS tire on my RT - for the REAR tire ... the General Altimax RT43 is a good rear tire choice also..... Touring (?) vs. Summer tire - the Summer tire will be much less effective below 50 degree's F.........and I think you meant ALL-SEASON tires and these will usually provide better WET road traction than a Summer designated tire ..... good luck ....

TIRE - PSI

OK, let me get this straight. It IS OK to run the rear tire (Altimax T43) at 20 PSI? I just pulled my head out and checked. I'm at 24K miles on the Altimax and it's about to be ryding season.

I do not want to get a ticket and don't want to have to worry that I'm exceeding that 'allowed' max speed by even one of those mile things, oh yeah, MPH. I have a couple of 5 K mile trips planned this ryding season...... Yes 20psi will work fine .....However 17-18 psi will be better. If you have the 215/60-15 size tire you will lose the 2 mph fudge factor that a Kenda 225/50-15 tire has built into it. I don't think there is any Police officer on the planet that is going to ticket you for going 2 mph over the limit..... We all need to be AWARE of what speed we are driving at ...period.

And, where is instruction on how to acquire, fill and post those travel maps of the US and Canada? I went a whole lot of new places last year.
..... Someone will assist you with this ....... Mike :thumbup:
 
I called both of the dealers near me and they will not put a car tire on my Spyder. I might have to find someplace else to do a tire when I need it. I don't want to go to just any bike shop they might know the proper way to do things.
 
Something important to know if you run the RT43 tire in 215/60-15 size. I have this tire. It is not compatible if you have a rear mudflap on your RT. If you hit a large dip or bump in the road, the tire will hit the mounting bolts for the mudflap. There isnt enough clearance because the tire is taller than stock. I had to remove my mudflap. And stupid me, I just ordered and received another RT43 in the same size because I like having the speedo accurate. I might sell it to a friend and buy the Khumo 225/50-15.
Joel, I also run the General RT 43 on my 2014RTS-SE6, I haven't had any problems, and I have 16,176 miles on the tire, and I have a lot of tread left.

Maybe you could use different bolts.
 
215/60-15

Will a General Altimax rt43 215-60-15 fit a 2012 rt-s or what size should I use
Yes ,,,,, if you have an after-market mud flap ............ use the smallest bolts possible ....some have had issues because of that ........... Mike :thumbup:
 
BK911.....

Not to worry. If they're too long they'll wear in to fit. :roflblack: I just put the 215/60-15 Altimax on my scoot and noticed it needs a little more throttle to achieve the same performance and torque. Did you notice that too? I think it's because it's a taller tire by a 1/2" or so.
 
abs problems.

Had to go with BK911, Peter and Spyder Ann. I just bought a General Altimax 215/60R15 and will install it next week. I pushed my Crappy Kinda to just about 7K and then installed a Kumho. I've gotten just about 20K on the Kumho with around 28 psi. I'll take the advice from BK911 and try 18 psi. on the Altimax, but that's quite some drop in air pressure. I put Federal Formoza on the front and I'm running 17 psi. and they seem to work ok.



I installed a 225-60-15 and my abs light is on the dealer says i need to stay with the 225-50.

You can go with the Yokohama S-Drive in a 205/55-15 as its exactly the same diameter as the oem tire. We have installed quite a few of them for happy customers. Its a great tire for the Spyder, wet or dry.
 
So I think the question is can you use a tire other then the original size tire without triggering an ABS fault? Lynn has put a 225 60 15 on the rear and got an ABS fault and his dealer is telling him that he has to go back to the original 225 50 15. I have not heard this before,do any of you know if this is true or is there some other problem. Or is there a way to erase the fault and go on with life with the 225 60.
BTW this is a 2010 RT-s

There are quite a few Spyders out there running that 225/60R15 size without ANY issues, ABS or anything else, me amongst them.... :shocked:

So I suspect either you have a different make of tire to any of those that others are running (since actual rolling diameter sizes can be somewhat different than the true size) & that you just might have a 'different than most' size... :dontknow: or, somewhat more likely, that you have something else going on that has triggered the ABS fault light. :lecturef_smilie:

And knowing that some (many?) Spyders come with a spacer fitted to the rear ABS Sensor to make sure that it is 'flying' the correct distance from the notched disc that it 'reads', and that the rear disc brake caliper and that sensor both need to be unbolted & moved when you remove the rear tire to fit a replacement, I'd guess that whoever did the rear tire remove & refit probably put the ABS Sensor Spacer back on with the spacer in the wrong position, so the sensor head is now the wrong distance from the notched disc & it is giving a spurious reading, which results in that ABS Warning! Or maybe the sensor wire was used to support or carry the entire weight of the caliper while the wheel was removed, damaging the connection between the sensor & the wire?? :dontknow:

Anyhow, while there is a slight possibility that the tire size itself is an issue, since there are so many Spyders running this size tire without any issues I doubt VERY MUCH that it's actually the tire size that's creating the problem here; I suspect that it's much more likely that the ABS Sensor has been fitted incorrectly &/or the wire or sensor itself has been damaged!! :shocked:
