Thanks for posting the pic - your setup looks great.

If you don't mind me asking, what is your rwhp (approx.), and how is your traction from a dead stop?

I like the look of 20's as well, but I would be afraid of the ride quality with that slim of a tire. I just bought 19's for my Supra the other day. My question to you guys is what tire size should I go with front and back? My fronts rims are 8.5 inch wide, & my rears are going to be 9.5 inch wide. What size tires do you guys recommend? I was either thinking 275/30/19 or 285/30/19 in the rear, & 235/35/19 in the front? I am also selling what I have seen in the picture below, PM me if your interested or if you want more information about them! I will also put an ad in the classified section for the wheels I am selling.


Oh & I don't want to roll the fenders, if that makes a difference. I am also installing TIEN coilovers as well,
Thanks guys!

sorry about the blurriness of the first picture

What is your rwhp? This should be your starting point to determine your rear rim width. Since you say your rears are going to be factory-spec 9.5 inch, I hope you're planning to limit your hp to factory specs too (320hp).

The current wheels I have on my Supra are 18's & they are 8.5 in the front, & 10 inch in the rear & I run 275 in the rear. HP came in at 350 last time it was on the dyno
Thought Im looking into having the rears widened cause I like them so much but they didnt come in a larger size, like a 10 or a 10.5 like i wanted.

If that's 350rwhp, then that's at least 28.7% more hp than stock (350rwhp /.85 = 411.76hp vs 320hp oem spec - please feel free to double-check my math). This means that your rear rims should have been about that much wider than stock...which is already about a 12" wide rim (11.5" would be fine, since that's the max that fits under the oem fenders). That'd be about 315mm-width rubber.

You can't run oem width rear rims and oem width rear rubber unless you're running oem rwhp. I know a guy that tried to run his stock rims at BPU on a MINT/PRISTINE <20K miles '98 Mkiv Supra, and within hours he ended up smashing it sideways into a big rock in a ditch. That's just ONE example of many. Every single component on the ENTIRE MKIV SUPRA TURBO has been spec'd and designed by Toyota to work together by highly qualified automotive engineers with decades of training and experience. You just can't go bumping up the hp and expect nothing else NEEDS to change. When you go BPU or beyond, one of the things that NEEDS to change is the rear rim+tire width. In turn, when that changes, the front rim width and front tire width must change together. It's like a symphony - you can't go replacing a violin with an amplified electric guitar and expect Beethoven's 5th to still sound right.

If the rims you think you "want" don't come in the right size, then don't buy them. It's that simple. There are LOTS of companies making LOTS of styles of rims that do come in 11.5"+ widths. Please let me know if you need help finding what you're looking for.

After you figure out how wide the rubber is that you need to run on the rear, then you can pick the front rim width and the front rubber width in proportion.

I used the tire calculator on discount tire site to help me determine the size tires I wanted. I wanted to say close to the factory spec diameter. I will also tell you the speedo change with the tire tire compared to what's spec. This will help you with picking a tire size that's close to spec. Hope this helps.
