Question/s about wheels - please help!
Hello guys and gals,
I am in the process of trying to figure out what wheel/tire combo I should go with... I have done my research but I am still not comfortable with how I am interpreting the info to pull the trigger. HELP! Here is what I know so far... I want to run 20 inch wheels and I am looking at the Torq Thrust II. I am thinking of a staggered look 20x10 in the back and 20x8.5 in front. Here is where I need help... OFFSET and BACK SPACING... What should I be looking for when it comes to this? Last question... What recommendations do you guys have on running the biggest tires in the back and what should I run in the front? Thank you in advance!!! |

Wish I could help. Backspace and wheel size confuses me. Someone will chime in. Keep searching, you may find an answer as well. Good luck.

I installed some 15" wheels with 4" of backspacing and they barely fit, but they did. Of course, wheels with more than 4" of backspacing will work if they have a larger diameter. If it were my truck, I'd remove the wheels and put a straight edge vertically on the face of the rear drum. Then using a ruler I'd measure the distance to the inside of the rear fender. The 10" wheel should fit fine if the backspacing is somewhere in the 3.5" to 5" range. This of course takes some work and study so that you don't waste time. If your wheels have a lot of backspacing then you might need to use wheel spacers so they don't tuck under the truck too far.

Re: Question/s about wheels - please help!
I would for sure do what Lugnutz65 said.
With that said, I run a 20x10 wheel with a 4.5" BS and the tire is quite close to the outside fender lip, I'll be trimming them back a half inch just to be safe. Any less BS for me would be an issue. I run a 20x8.5" wheel in front with a 5.25" BS, I could run less but I also run a PB front suspension which is narrower than stock. If I was ordering custom BS expensive wheels (which I did), I would measure my own truck to make sure because once you buy them they are yours. ![]() ![]() |

Re: Question/s about wheels - please help!
Just for clarity, in the diagram shown, the GREEN arrow showing POSITVE OFFSET is pointing AWAY from the truck. It would be a shame to get that part mixed up.
Based on what DLW says above, it sounds like you should try 5" of backspacing since he's a bit worried about tire rub with only 4.5" of backspacing.
