Default Lets talk tires and 15" rims

I think its safe to assume most people here are running 15" rims and 225 series tires.

Right now im running 15x6.5" Heliums with 205/50-15 Azenis.

I would like to pickup a set of 15X7" wheels and run 225 series tires.

After searching around I see that there just isnt much available in 225/45-15 and there is alot more available in 225/50-15. I think that might be too tall though.

What are you guys using with 15x7? Where did you get them?

I'd think you'd want 7.5" to run 225, and preferably 8"
Why not get 7.5-8" rims and continue to run 205 azenis?

15x8 6ul's with 225/45/15 RS2's. That seems to be the hot setup these days.

I know plenty of people run 225 on a 7" rim. 205's on anything larger than 6.5" looks cr.net style to me.

I like this- http://i6.photobucket.com/albums/y22..._test_fit3.jpg

well, from what i've been seeing, the rs2 is a skinny 225. so if those are your target tire, the 7" rim would probably be fine. otehr tires, you might want to have someone measure the width for you.

i've never understood why consistent sizing should be this friggin hard, but apparently it is... tires, shoes.. they all just have their own rules apparently

I wouldn't want a 225 on a 7" wheel, but then it's also going to depend on who's version "225" it is. A performance 225 will be wider than a standard 225. Performance 225 on a 7" = squishy squishy. Likewise a performance 205 will be wider than a standard 205. A 205 azeni fits well on a 7.5-8" wheel. As does the RS2 and KDW.

Both tires on 15x8


Does that look stretched to you?

Here's what an engineer/wheel designer had to say about it

For those not acustomed to race wheels it's en eye opener the first time you yank the wheel over with the wide wheels.

I dont get tire sizing at all... I have found some 15X6.5 rims that I like, so which size tire should I get to match the 195/50/15 look, just a little stretch?

155's


As soon as I have money again...Emilio will get it for some 9's i so deeply hope.
I want two sets, one for some Hoosiers (275's) one for the streets (225's or maybe a good 245 if it comes out by then).

I was planning on running a 225/45/15 on 15x7 Kosei K1s, I'd prefer to run 215/50s but the selection in that size sucks *****.

I had an old set of 14x7 wheels I borrowed from a vw guy and I put my 195 T1R's on them. I still slid around a whole bunch. The front end just would not grip.

This time I'm trying the 225 15x7 route. There were several other Miatas at the autocrosses last year running the same size setup and they seemed to be fine. I'll see how well it works for me this year. If I don't like it I'll switch things around.

Call Discount Tire Direct. When I bought mine, they didn't show them online, but they had them on order, and I paid for them ahead of time. They offered to put my name on a list, but I felt better paying for them and not worrying that I'd get missed.

By the way, they have 10% off on their site now, right on the home page.

Ben, +40.

I think Emilio got tired of mounting 2738972894792834q tires every time a wheel shipment came in. I don't know the real reason, just speculating.
