offsets, and tires sizes for my SC...

[BOOSTED86]

So I have an sc300, 1993. I want to put phatty tires on it. phatty in the sense of width, like show car status width, like, wholly *Censored**Censored**Censored**Censored* thats wide status, but still streetable. So what my question is, is how phatty can I go on the rear, and how phatty can I go in the front?

the next part of my question is: I was planning on getting 19's what width should they be? 19x?. and what size tire should i get considering I want the tire wall to be this tall (???/whatever this one is/19)



so, rim size and tire size taking into consideration different width rim and tires front and back.

thanks for your guys's time!

Drifters don't use phatty tires because they're phatty expensive, and the 19" wheels are fat in terms of weight.

I don't think a single one of us has any idea because we've probably never seen 19s on a drift car. Stick with 18s; they're cheaper to replace when you hit the inevitable curb, rock, cliff, or k-rail.

whats the difference between using spacers and offset on rims where tire width stays the same?

which is better?

19x10 / 19x8.5 sit perfect

30's in the rear and 35's up front

Rims with the offset you want are better than spacers: less parts, less "cobbled-together-ness", less weight. There's no difference in terms of where the tire meets the road compared to the position of the suspension, but unless you absolutely can't find the rims you want in the right offset, or you already have the rims, I would urge you away from spacers.

The wider the tire and higher the offset, the more scrub radius you have. Too much scrub radius is bad for rolling resistance and twisting force on the tire under steering input (heavy steering).

You can get huge wheels that are light like the Volk TE37's, but 19" is just going to be a lot more to deal with for nominal gains in looks and losses in performance. Even econo-sport tires like Kumhos are going to be like $100/tire for 19's while something nicer like Falken Azenis could be the same price for an 18" or 17" wheel.

The shorter the sidewall is the more work you're making the suspension do rather than the tire. At the same time, short sidewalls improve response, although this may not be noticable to the beginning driver.

On a side note:
Tire sizes like "250/45/R18" refer to "tread width/series number/wheel radius" where width is in millimeters and series number is the aspect ratio (percentage) of section height divided by width (in this case, it would be about 112).

Hope this helps...
