Wheel and tire sizing help!

Hey everyone,

I am planning on buying new rock crawler wheels and tires for a prerunner x cab. Can you tell me if the following will look close to stock/better? Also please let me know if the sizing is wrong:

Wheels:
1. Rock Crawler series 51 15x7 6 on 5.5...3.75in backspacing (what is the correct backspacing anyway on the stock wheel?

Tires:
1. Pro Comp All Terrains 31/10.5/15

So will the 15x7 w 3.75 in spacing be the correct wheel (like stock) and is it correct?

Also is the 31/10.5/15 going to fit the wheel and look good on the truck?

One thing I noticed was that the Rock Crawler series 51 isn't 'Street legal'...why is this? Do people run these on the street and is it safe?

 

I do know that if you have a 2005+ prerunner or 4x4, your 15 inch wheels are no good. The caliper on your truck is too big, and won't clear the wheels. Some 16's don't even fit without shaving down part of the caliper, which some people don't like to do for obvious reasons.

 

yea 15's are not a good idea on any models, my calipers required shaving on my '95, you should opt for at least 16's
