Tire and Wheel fitment Q&A

cre · 07-23-2007, 09:31 AM

What width? I just ordered some 17x7's (yeah, I'm pooooor) and I'm trying to figure out what size tire would fit best. I'm thinking 215-225/45.

Japanese supra tt · 07-23-2007, 09:33 AM

the fronts are 17x8 and the rear are 17x9.

i just put some 215 federals on my front and they are flush with the lip of the wheel.

but if you wanted a little bit of a stretch, which looks nice, then 205s on a 17x7 would be sexy

cre · 07-23-2007, 09:42 AM

Heh, no, not into the stretched look, nor the "I got a great deal so what if the tires are 4" wider than the rims" look. lol. I'm looking for something that'll be fairly flush, have a decent size contact pad, but won't have tons of sidewall flex when cornering hard. I figure with the small sidewall I shouldn't really notice any more slop in the sidewall than I do with 215's on my sawblades.

Japanese supra tt · 07-23-2007, 09:45 AM

well if the tires are slightly stretched then it would reduce sidewall flex =D

but yeah 215s fit my 17x8s flush, so for 17x7's id go a little less wide.

Bummer, so the great deal I could get is equal to:

Figures. Oh well, the rims aren't here yet and I don't have the cash for the tires anyway, so I'll have time to look around.

why only 215?

thats a little too skinny for 8'' wide rims
215 is what i got on my beater

u said u got 17x7
i used 225x45x17 in the front
and 245x40x17 in the back

less sidewall to reduce flexing, but enuff to be safe with potholes
and wider tires give you more grip

and one question, for japanese tt
using harder compound tires, yes they last longer but
do u have any problems with grip if you do a high speed corner?

you have to take into consideratiion the offset of the rims you have on your tires to not just how wide the rims are

btwilson86 · 03-21-2008, 03:58 AM

Offset is the measure of distance the mating surface of the hub is from the center of the wheel's width (distance between outside (face) of wheel and the inside edge of the wheel). Offset is typically measured in mm, and a + offset means the hub is closer to the face of the wheel, and a - offset means the hub is closer to the inside of the wheel. Most aftermarket wheels you buy will need to have about a +35 to +40 offset (I believe that is for 8" wide wheels- Wider wheels should have a lower offset).

Keep in mind, if you are concerned with true cornering and sidewall flez, profile in-and-of-itself is NOT the only consideration. The tire construction, design, and purpose is more important. Save your money for a while longer and get a good performance tire. It is always a trade off for really good grip Vs tire life but a good stiff sidewall will cost a little more. Most of the 'bargain' tires wont have that so I advise be patient, save your money, and get a proper tire. Since low profile and bling are in voque, there are many crap tires on the market which are just for looks. I had a set of really cool looking Bridgestones that came on my 2005 Subaru Legacy GT. They looked cool but felt like they flexed so much they were going to role off the rims. I replaced them with Goodyear Eagle F1's. Much better and may be a good choice for your Supra but dry weather only. Actualy got them pretty reasonable from Tirerack.com.
If you really want a great tire get Toyo RA1's...GREAT performance but may not last too long on a daily driver. (I have 225/45/17 on 8.5"rims)

Bottom line, try not to get cheap tires, but you can shop for quality tires and save money. (Another brand to look at is Nitto.)

i dont have any hard compound tires lol just regular drift sets.

and i use 215s on my front because it makes the tire "stretch" to the lip of the rim and gives a little less sidewall to deal with, and ive never had any problem with them losing traction, esspeccially federals, the tread is insane.

eh?
