tires and wheels What is a good tire size for 13x7 wheels?

[PSloan]

im looking at 225 45s. Any thoughts? Should I go wider? Taller?

I don't know about the fit, but your speedometer will be about 10% off with that size, so you'll want to keep that in mind. The tire will be smaller in diameter than the stock size, and when you speedometer reads 60mph, you'll actually be going about 53mph. Roughly.

A 225/55 would be a lot closer, but I don't know what (if anything) is available in that size...

I believe that the standard E21 turbine wheel came with 185 75R13 tires.

You'd have to be careful that going down to a 45 series tire will decrease your circumfrence and therefore throw off your speedo. There's a tire calculator on the FAQ and other places - try finding something that will fit the car and keep the same circumfrence so your speedo remains accurate.

I didn't think about what size tires came on the E21 wheel. Wasn't the stock '02 tire a 165/80 13 ? That's what I based my reply on.

The best tire calculator out there in my opinion is here: http://www.miata.net/garage/tirecalc.html

They arent 320i turbines. they are 13x7 deep dish wheels made by western wheel company. Thanks for the tips though.

i run 215/45/r13 kumho v710 on 13x7.5 wheel.

225/45R13 and 225/50R13 Hoosier tires also fit on 13x7.5 but they have provisions for narrower wheel.

you might have to sacrifice tire pressure for wider patch if you are running too narrow of a wheel.

look at the specs of the tire manufacturer for their wheel size recommendation.

I am lusting after a set of 13x7's. Here is the tire of choice in my opinion:

215/50 Of course it all comes down to what you will do with the car.

I'll sell them to you if you want. Shipping would be brutal. After thinking about it - im not sure i want to run flares. Will these fit under without flares???

Buy DAPBMW's flares off the FAQ store - they are badass and not too much like the turbo ones IMO. Just enough for you to shove something nice under there.

tires were sourced from germany. avon also makes this size tires but none are available in the us or canada. on a 13 x 7 you have at least a few sizes from sumitomo, micket thompson, bfg, firestone, falken and hercules

1.195 60 13

2.205 60 13

3.205 50 13

4.215 50 13

I'm really going for the sleeper look. My 72 will be badged, trimmed, and painted like a 1600 with a turbo m10. Flares would take away the element of surprise.

On the other hand my POS doesn't need to be cut prior to installing the flares as I'm just letting the rust do the work for me. I'll have flares on the scariest looking POS 2002 around!

Whats the offset? Post a pic maybe I'm interested_ i really want ATS classics though. At first I'd fit a good set of 205/60 13's. If those fit and it seems that a shorter tire would fit then go for the next step down in diameter and up in width.

I'll see if i can get some pics for you.
