why run 15X9 wheels and only use a 225 tire?
So bash away if you must but what is the point of using a 9" wide wheel and then fitting a 225 tire that has only 8" of tread width? Is there really much more grip than a 7.5" or 8" wide wheel using a 205 width tire that has around 7.7" tread width? Or for that matter run the 225 on the 15X8.
Am I totally missing the point or is this just aesthetics. |
i know 205's on a 8 is somewhat stretched, id assume a 225 on an 1" wider will would be bout the same....
|
Find a wider tyre in a 15'' that isn't a slick. You can't.
|
No, as far as I know a lot of the people with 15x9 6UL's on here run 225. I believe it's mainly because of tire selection in the 225+ range. Don't quote me on that though, I only have piddly 7" wheels.
|
1. With the exception of the 275/35 Hoosiers, there is no tire in the correct diameter wider than 225mm for a 15" wheel
2. 15x9s with 225s are faster than 15x8s with 225s, end of story |
isnt the tire selection of 15's alot better than 16's this is the problem i am having. im wanting to bump up to a 16x9 and looking to run a 245.
Tire talk has always confused the fuck outta me...:facepalm: |
i have always had the theory of if a tyre is stretched the tread of the tyre is pulled flatter giving you more rubber in contact with the road, or is that just a excuse to have stretched tyres lol

I still don't understand why no one makes a 245/40/15 in a street tire. I guess it wasn't too long ago that you couldn't find anything wider than a 205. You would think that since the 225/45/15's seem to be constantly sold out that someone would figure out that there was some demand for a wider tire. |
this was the widest i could find with a sensible profile, its a semi slick track day tyre but road legal in the uk. dont know if it is on your side of the pond but they are trying to make them illegal on the roads here by 2012, how gaaaaaaaaaaaaay

Were you planning on posting a link or picture? Cause you didn't.

Yes, that was the spec tire for SM last year. They hated it for endurance reasons I believe, and they're back on RA-1's. Like Sav said, there are only slicks available in 225+ sizes. That's a shaveable slick, but still a slick. And still only 235.
|
i know i am collecting my first mx5 in a few weeks when the guys sort out his other car and i have been looking at 15x9 wheel ( links please coz im finding fuck all lol) and then a tyre to fit it. i was going to use a semi slick anyway as i wanna get the most out of them before they ban them. Its wierd that a wheels size exists but not a tyre size to match
|
I did say stock diameter for a reason. 24.25" is not stock diameter by any stretch of the word. It's hard to fit a 225/50 on the front of a lowered NA, 235/50 would be nearly impossible. I bet you lose time between a 225/45 and a 235/50.
|
agreed with just about everyone here: because pretty much nothing else is available in 15"
|
2. 15x9s with 225s are faster than 15x8s with 225s, end of story[/QUOTE]
Does anyone else agree with this? seems that a 15X8 with a 225 would be a better choice and a lighter set up as well. I was also just concerned with street tires. So I guess I was just trying to find out if there was any real benefit from the 15X9. Thanks for all the input. |

He did say end of story. You should trust Sav has tested this a few times at the track. |
My question then is, which tyre should be used on a 15 x 7 or a 15 x 7.5 wheel?
To be placed on a 225 WHP turbo NA car. I'm thinking maybe, 205's up front with 15 x 7 wheels and 225's in the rear with 15 x 7.5 6UL wheels. What do guys think? |
7's will fit 225 iirc. just run 225 all around
