What size tires for 18" Base Wheels? (tracking)

flashburn · 03-16-2011, 12:00 PM

So I have a set of the 18" base wheels that I want to put tires on for tracking. I'm going to get RE-11's, but I'm not sure what sizes I should run. I'm running 15/20 spacers, not sure if that will matter or not.

Also, should I go for a square setup or would it be better to go with a wider tire in the back?

Square setup is mo' betta. What is the width of the base 18s?

flashburn · 03-16-2011, 12:14 PM

After doing some searching, it looks like the widths are 8"/9".

m4a1mustang · 03-16-2011, 12:16 PM

Hmmm... I don't like that one bit! If they were 18x9 all around you could do a square 275 width setup.

I think most of the more serious trackers here are running 285s all around but thats too wide for those wheels.

flashburn · 03-16-2011, 12:17 PM

Yeah, that's why I was thinking for these wheels a square setup might not be best.

I heard the new Boss has a square setup.

flashburn · 03-16-2011, 12:23 PM

Meh, if only I could afford it.

Anyway...

I'd just put the widest RE-11 you can put on the base wheels. That'd probably be the best setup with what you have to work with.

flashburn · 03-16-2011, 12:35 PM

Yeah, that's what I'm thinking as well. Trying to figure out what's the widest tires I can "safely" mount on them. I've read a few people say they've gone up to 255/275, but I'm not sure how much that would be pushing it, since this will be specifically for the track, the setup will be stressed pretty heavily.

m4a1mustang · 03-16-2011, 12:37 PM

As long as you are within manufacturer spec for the tire you will be OK.

flashburn · 03-16-2011, 01:00 PM

From looking at Bridgestone's site it looks like the max I could run is: 245/40R18 and 275/40R18.

Red__Zed · 03-16-2011, 01:30 PM

you should be able to get star specs in the sizes for the base rims.

flashburn · 03-16-2011, 06:40 PM

Why the Star Specs? How do they compare against the RE-11's? Also Bridgestone has a $70 rebate right now, so that's another plus.

cossie1600 · 03-16-2011, 06:48 PM

if you want to go fast and can drive, do not get stagger. if you are worried abut safety, run 255 or 265 all around. i run 285 all around on the stock 9 and 10 and on 9.5" wheels

flashburn · 03-16-2011, 06:51 PM

According to the tire spec's, a 8" wheel isn't within the specs of the 255 size.
