what size tire should i use.

[the_eclipse_1]

i'm getting a set of 18x8 wheels on front and 18x8.5 on the back. a buddy of mine told me that you can go a half an inch bigger on tire size so that you get a lower sidewall look. I allready know that i have to mod my fenders so that this tire and wheel package will fit i'm working on that now. so if you could help me out on what size tire i should through on that would be good. the lowering kit drops my car 1.25 in it's the tein flex kit. thanks

Ask your buddy. :laugh:

You know of course that larger rear tires will make you a target for criticism.

8 inch wheels will want 225 or 235's. The 8.5's will want 235 or 245's. 245's will be hard for you to fit without rubbing. The narrower selections may perform a little better. The wider ones will be, um,... wider.

Good luck.

Try to stick to close as stock as possible. Remember Mitsubishi does make rally cars so they definately do know suspension...Here is a website that let's you calculate...Just remembe try to keep the rolling diameter EXACT.

Actually you only need to match exact diameters front to back with AWD. It won't bother a FWD vehicle.

I would have to disagree with you.... Can you do a correct offset to fit larger tires? And getting too large of a diameter changes your overall gearing ratio. Smaller diameter, shorter gearing. Larger diameter, longer gearing.

Also, I am under the impression that with larger tires, the rotational mass is pushed outward more. There's more rim which may be heavier, but the rubber which is in general pretty heavy is pushed more outwards in the rotation spin, which makes it harder to spin.

When picking tire sizes, i'd try to get as close to the stock diameter as I could, but if I couldn't, i'd go smaller to get that gear ratio change in my favor. Unless you do alot of highway driving, the larger diameter will help you cruise at a lower rpm.

Let's not get off on too many tangents at one time. The focus of “the eclipse 1’s” set up seems to be appearance not performance.

The implied question (in my opinion) is “What size tires can I put on my car that are larger in the rear and make my car look really cool, without making it disintegrate, explode, result in personal injury, melt through the earth’s core, etc.”

Performance aspects notwithstanding, I doubt that slightly larger diameter wheels on a front wheel drive car would cause any of the above.
