Toyo Tires - Plus Sizing

That site gives you general rules of thumb for when you increase rim size. Also, you can use tirerack.com and they help with sizing tires, too.

17" should be good! A generally standard size is 245/45/17. My 2000 GT Spring Edition uses this size. I also have a 1994 GT and I just bought rims and tires for it! They will be here Tuesday!!!!!!!!!!! I am old school so I wanted FAT tires on the back so, I went with 17" 245/45/17's on the front and 17" 315/35/17's on the back.

Holy crap those are fat tires!! What is that, like 12" rims?!? That's pretty sweet! So how did you fit those in the fender? Did you have to use wheel spacers? Small offset? Do they stick out the side?Post pics when you get them on.

well 17 sounds nice so id be lookin for 17 inch tires and rims. Now what would i have to change on my car if I get the bigger tires? Wont it affect my speedometer? Also Im planning to lower the car with Eibach springs this winter, will there be any difference in the drop if the car sits on 17s instead of the 15s?

You don't have to change anything if you get the right tires. Check out the sites I listed and they will help you to size the tires. I think you will be looking for 245/45-17s all around for rims with a 17" diam and 9" width. You could also widen the back tire/wheel (since it doesn't turn) and still fit. In that case, the back should be a 275/40-17 with a 17" by 10" width rim.
Sizing the tire properly by going with a lower profile (aspect ratio) for larger rims is what keeps the overall diameter of the wheel & tire the same -- so then it won't screw up handling, speedo, etc. Check out this site to see how the tires compare: Tire size calculator
Also, Eibach already did all the math to lower your car properly. They lower it enough without compromising the ride. I would go with the Pro-series (kit, springs, whatever you choose) if you are driving in town at all. I have heard the Sport-series is almost too low and you can bottom out (tire hits the fenderwell) in deep holes.

you have awful tires now....

even when i was running stock wheels on my 99 v6 i had 225/55/16


now im running cobra Rs with 275/40/17 on rear and 245/45/17 on front

looks killer


the 275 on the rear really sets it off... got the set for 350$

[AutomaticAK]

Thanks for all the info Silver
so chattanoga, you really got a set for just $350? where did u find that deal? i went on tirerack.com and the best i could get for the 17s was like $750. that was a set of 4 tires + 4 rims

[chattanooga]

lol


i got 4 Cobra R wheels with tires already mounted for 350$


i can get you a set for 400$ if you wanna drive to chattanooga to get them


everything for mustangs is cheaper here... unless its made by weld i could trade my 5 lug cobra rs for some decent weld prostars... lol


But i have two new tires and the fronts are decent.. but need replacing

[AutomaticAK]

wow chattanoga is far im in DC.
you dont know any good sites that got em for cheap?

If you are going more than +1 on tire sizing, you need to get your computer reprogrammed for the new tire size or your speedo will be off. Most shops can do it for a small fee......

Yes, your car will be alot slower because of the rotational mass. My suggestion would be to get a set of Weld Draglites or Prostars. Even the Summit and Jegs generic rims(99-119.00 each) look great on our cars, and they are much lighter. Too many people put heavy rims on their cars and then complain that it is slower. Well, yeah.....

[AutomaticAK]

damn i cant have that...my V6 isnt that fast rite now and im not trying to take a step back. would 17" or 18" make a difference on speed or is it just the weight of the rim that affects the speed? any idea on what the stock rims off a 205/65/15 weigh?
