R Comp tire info and help please.

[James@SpecR]

Since I have modified my car straight out of STX for this coming year, I plan to run R comps for SM.  I have never driven on them or owned them, and I understand in some cases the sizing/dimensions are different than regular tire sizing.  I ran 255/40/17 Direzza Z11 on 17x9" wheels last year, which fit well but rubbed slightly, I am looking for similar sizing but no taller and no wider, potentially slightly narrower.  Suggestions on where to start or specific tires to look at?

Go to the Tire Rack web site and you can review all the specs on all the tires - Hoosier, Dunlop .....  Check your tire width, dia. etc. then compare to the Hoosiers....   Something I would check into is the 275-50-15's .... if they fit you'll get a lot of grip!!!  Hoosier is, of course, the fastest one ..... There are other R's available like the Kumho V710's but you are giving up perhaps 0.75 sec. on a 60 second run on them ... Toyo has some too but are even slower .... BFG R1's .... think all but the Toyos are on the Tire Rack site.....   For local events you could save money by running something other than Hoosiers ... but even then ... there is nothing to compare to the purple "crack" ...

Thanks Reijo.  I did hear that Hoosiers are generally the fastest, I don't really plan to leave Alberta though so I may look at the cost difference and go with something else.  15" wheels are very difficult to fit over my brakes without the right spacers and offset, 16" is possible but width wise I am already struggling to fit 255s and a widebody kit is just out of the question.

You are welcome.....and the Hankook is the other one you should look at.  Ventus Z214.

You might want to look at the 245 size ... some times the R's are a bit wider than a street tire ... but the specs are all on the Tire Rack site ...   You could also ask around locally to see if anyone has one used tire to use for fitment ...

I am probably going to do a 16x8 wheel with a 245 wide R comp I think.

[Reijo]

There should be some S2000 guys around with 245 wide 16's around  (Murray maybe?) .... don't know if I have any of those left lying around ...   In fact, I think Murray might have a set of Hankook Z214's in a 245-16 for sale ... Murray?

I have a set of Z214s with 36 runs on them, and they are more than a year old now.  Currently mounted on my AP1 OEM wheels.

Definitely for sale -- cheap too!

245!?  Aren't your wheels just too fan boy friendly?

I thought 285's fit these cars without issue...

My car is a anomaly, I rub with 255 Z11s on the perfect offset wheel.

And what do you mean fan boy friendly?

[E6Cueman]

ha.... just suggesting that they were more negative in offset than the needed to be.  Car looks good.  That is all.

They aren't that aggressive, +35.

Next time Rocket Bunny with -50 offset?

[E6Cueman]

just because I see you lurking... 245's will be fun, but will it be very fast? Is it worth it?

Orrin has 285's... but his car is cut up to make it work?  I have a really nice and gentle Easton baseball bat.

Eh I figure since I am running in SM now I might as well get some R comps for the best chance possible.

But wider is better .... and faster.   

[James@SpecR]

But wider is better .... and faster.   

Yeah, but also more expensive (extensive fender mods required) and I just can't afford nor want to delve into cutting my car up right now.  It hasn't even been in service for a year yet.

Hopefully down the road though!
