    Default Federal tires

    Is anyone running Federal tires on the rear, and what size are you running?

    I did back in 2010 ..... I wasn't impressed with Wear or Traction ........... There are currently some excellent tires now ...... Mike

    General Altimax RT43 ( the T speed rated model is the better of the three sold ) and the Michelien Premier ...both in 215/60-15 ......... I am going to test the Pirelli P4 Four Seasons PLUS , when I change tires this winter , I think it may be better than both of the above ............. Mike

    I haven't seen a Federal rear in a 225/50 or 215/60. I am running the Kuhmo AST (225/-50-15, it has the H speed rating like the Kenda) and am happy with it. I would have preferred to find a V rated option for better traction but couldn't source one. When cold it spins up just as easy as the Kenda did, but once warm, traction is much better. Even when it is spinning, I get more forward motion than the Kenda gave when it was spinning....

    you must be referring to the treadwear rating? Cuz a V rated tire is built for higher speeds than a T rating ( 118 for a T and 150 for a V). I know the speed is a non issue with our machines but the compounds used in higher speed rated tires give better grip. ...

    No I wasn't ........ I agree V is higher than T........ But - Higher speed rating has NOTHING to do with traction / grip ....... of course you may have a different understanding about Tires, but qualifications are based on Schooling & training for over 25 years. If your info is based on what tire Salesman, / women are telling you , my experience with them is 95% are clueless about the product they are selling ........... Mike

    Was in the business for 20+ years myself. Think about it, when was the last time you saw a T rated tire on any vehicle that has any type of elevated handling capabilities? You haven't. There is more to a speed rating than just the ability to withstand deformation and the heat generated at speed. Mfg'ers know that with the demands put on higher speed rated tires comes the necessity for increased traction.... This is why higher speed rated tires usually carry a lower treadwear rating. Their compounds are grippier for increased traction.

    Many of us ride the Yokahama S-Drive 205/55/15 with excellent result. Traction has always been excellent. I have about 8,000 miles and may see another 8,000 before a change is needed. iíve heard the size is very close to the originals.

    Thatís an easy mistake to make. Seems when you search on a specific tire size they will bring up just about any size tire.

    Is it hard to find our tire size is that why people run a different size? I've got a 13'RTS and I'm getting close to needing a new rear. Thanks

    The main reason people are using the 215/60-15 in. size is because there are very few 225/50-15 tires to choose from. And this size will make your speedo almost perfect on the speed reading ( OEM size reads more than you really going ) if you get a General Altimax RT43 in 215/60-15 you will be very, very happy with the way it performs ....especially if you only put 17 or 18 psi in it .... It's a strong Auto tire and doesn't need higher air pressure to work correctly ........... Unless you have already done a rear tire swap your-self, I would make sure your Dealer will swap an Auto tire ........some re-fuse .....good luck .... Mike

    I have been looking at rear tires all winter. In comparing the tire sizes on a web site the 225/60R/15 was listed as being over 7.75% bigger in diameter than the 225/50R/50. That site recommended not going over 5% larger in diameter over the tire size that came on the vehicle. What is your take on this suggestion?

    If you're going to go with a xxx-60/R15 tire go with the 215-60/R15. There's no good reason to go larger diameter than that. The 215 fits good. As far as width there's no problem going one size narrower or wider than OEM. You really don't want to go 2 or more size over or under.

    Well I wouldn't consider the 225/60r-15 size at all ..... The swing arm on every Spyder that I know of ....is very close to the tire using a 225/50-15 or a 215/60-15...... So if you go taller AND wider than that , I think you are asking for trouble ..... And I don't just think out-of-the-box ....I LIVE out there ...... But while I try things because I think they will work .... I keep in mind .....What is the benefit of this change or modification ..... The footprint you will attain using the 225/60-15 ( it will be an increase ) is so small ....the word " infitismal " comes to mind...... As I commented in another Thread about increasing tire sizes .... The Spyder is NOT a Hayabusa, which is a Mtc. that could more than likely actually benefit from a bit more traction if used at the Drag Track ....... I gave you one of the best tires our Spyders will benefit from ..... There is only one other person on this Forum ( that I know of ) who is as qualified as myself to give expert advice on using tires on our Spyders and that is Peter Aawen. Not boasting or BS-ing on this...... Mike

    Why do people change away from the factory size of 225/50/15? Is it to keep the same brand on the front and back? What difference will it make to go to a taller tire like the 225/60/15. The tire width is the same 8.9" but the sidewall is almost 1" taller. Also, the speedometer would be about 5 MPH slow that you would actually be doing at 70 MPH indicated. Is there something that would be too close and rub? I have the automatic ride height shocks so I guess I could always raise the ride height if absolutely necessary.
