Choosing a tire size....

[flexnix]

Going with 20x8.5 wheels. I'm not a fan of stretched tires.

I was wondering if I could run 245-35-20 all around with Eibach Springs installed. Also, wondering if that tire size would be OK if I ever go with H&R spings.

Thanks in advance.

Thanks!

Though I'm not sure it takes into consideration if I plan to lower the CC. I'm going with Eibach springs and don't want stretch.

This will calculate the new tire size - vs - stock size. You will see the difference in the over all diameter, and make adjustments to get as close to stock diameter as possible. I am only .04cm off.

I know the OP doesn't prefer stretched but here is my .02 cents.

I hope the owners of the cars below don't mind me using their cars as an example (and if they do, I apologize) but this is what 245/35 looks like on 20 x 8.5. Personally, I think it's too much rubber on a 20" wheel.



Now w/tires on 20s that are more suitable (granted they are stretched and my preference):
Dion's 235/30 on a 9:


235/30 on 8.5s on the front wheels only:


If you don't want stretched tires, I would do 235/30 or maybe a 225/35. If you want more rubber, I would go down to a 19".

And if you're into beefy tires, forget everything I said.

I wonder what suspension he's running. Seems like H&R springs.


I wouldn't mind stretched tires, but for BBS LM's...I've always liked chunky tires on the LM's. Any other wheels a slight stretch is ok.

They're BBS LM Reps, not originals. I'm not that baller.

I was going to stretch mine, but I do alot of highway driving, and I heard that stretching is not good for highway travel...
So, i have a little bit of rubber on my set-up.
Just my .02

I don't think stretching is good for any kind of travel

People stretch for fitment and hellaflush.
