Rear tires

[Plarimer]

I’ve seen many posts about using regular car tires on the rear of a spider RT. Not being that familiar with the mechanics, are you talking about any rear tire of equal size, such as a Goodyear eagle or Bridgestone etc?

Just about. There are several that are "favorites", not sure about Goodyear and Bridgestone.

The General Altimax, Federal Formosa and Vredestein Quatrac 5 are the top runners, I believe.

I put a Vred Q5 on my wife's RT. Wanted to make the speedo a little more accurate, so I went with a 205/65-15. Speedo now agrees with the GPS speed, but the odometer is off about 2%. I'd rather have the speedo accurate, it's refered to MUCH more often than the odometer.

You can even uses some tyres that are not labelled the same size as the Kendas, Plarimer. The way that different tyre manufacturers measure their tyres means that a 225, or a 205, may both be roughly the same width as someone else’s 215. The best thing to do is go by the brands/sizes recommended on here by those who are using them. I had a 205 Kuhmo on my F3-L.

YES! Both of those Tire Brands underlined ^^ make & sell tires in sizes that will fit and work pretty well on your Spyder, as do many of the other 'better known' Or 'Brand Name' Passenger Car Tire Manufacturers too! hyea: Can't necessarily say the same about some of the lesser known or more generic brands, but that's really only because there's simply too many of them to check them all out! :gaah:

And as has been said many times on the Forum previously, if you run similar sized but alternative make Passenger car tires at or close to the right pressure for the lighter load of the Spyder, they pretty much ALL work a lot better than the OE spec Kendas in pretty much all respects, altho some may be designed and work exceptionally well with respect to their particular strengths &/or designed/intended use. There are some reeaaally sticky 'track only' & 'road/track' tires out there that are sooo sticky that, once warmed up properly, will stick like the proverbial to a blanket and waaay exceed the capabilities of your Spyder :shocked: but their wear rate was phenomenal and obvious to the naked eye even after just one day/less than 1000 miles of use! :yikes: That's sorta why I've mainly concentrated on 'Sport Touring' tires, and because of our wide range of road and weather conditions, even with those I've been targeting 'All Season' tires or at least those with pretty good wet weather capabilities! :lecturef_smilie:

Also, Peteoz mentioned the size thing - here in Oz we do have limitations on how much you can vary the tire sizes from OE Spec, but that's based upon the tires Rolling Diameter and not the Nominal Size printed on the sidewall, cos as Pete mentioned, one manufacturers tire (or even different tire types/labels from the same manufacturer!) may differ a LOT in actual size when compared to another manufacturer's tire (or even their own but a different label/tire type!) with the same Nominal Size - the biggest difference I've seen so far has been a variance of just over 50mm/2 inches in rolling diameter - and that was between 2 tires of the same type/similar tread patterns with the same Nominal Size printed on the sidewall!! :shocked: So look for similar 'revs per mile' when searching for alternative tires, or compare rolling diameters, from the tire's ACTUAL specs, not just from a generic 'tire size calculator' or comparison chart on the internet! :thumbup:

Y'all know what I usually say here, so this time, I'll just say Enjoy! :cheers:

:agree: & :agree: ..... Let me add something about " STICKY " tires. On my 2014 RT, after the Crapenda's wore down I got a good deal on a pair of Toyo Proxes t1r's in 185 / 50-15's .... I had to add washers and tweek the front fender brackets, but I got them to fit :clap: .... without question these were and are still the stickiest tires I have ever had on any Spyder I've driven ..... However I found the NANNY VSS wasn't as happy with the " G " forces I could pull in the twistie's ..... I ( and a few others here ) will say I can drive my RT pretty fast ( in the twistie's ). .... it seemed to be too easy to trigger Ms. Nanny into applying the brakes .... with my 175/65-15 Altimax RT 43's I would get a Warning blip but not applying the brakes ... . this makes for much smoother driving, which translates to higher speeds.... good luck ....
