tire size clarification please

[Hellz]

so i have done alot of searching on this issue. i just can get a clear answer. alot of the posts says you can do this, but the next post says you cant.
one says you will get some tire rubbing, and the next says that its minor, the next says you need to pull out plastic.

so here is my issue.

im looking to purchase some KMC Rockstar rims (yes, more rockstars)
20x10

for tires, i want to run with a 37 inch tire, and this is where my issue is.
can i run a 37x13.5 inch tire without any issues?
stock H2. no lift with the air ride in back ( i know i need to move the sensor)
would i need to move to a 37x12.5 instead.

im fine with some light tire rubbing as long as nothing is getting damaged.
i can always crank the TK to raise it a little, but that wont do anythign for the width issue.

so can someone give me a solid answer on what im safe to run without any rubbing at all, and what might be a little rubbing.

i am interested in Mickey Thompson MTZ tires.
i like the look of the Nitto MG, but dont like the loudness or the crappy tread life. the Toyo OC are not bad, but just lack the aggressive look.

thanks in advance

thank you!!!

did you have to do the lift because of the tire/rim combo, or just because you wanted it lifted?


any rubbing issues?

With 12.5 wide tires you will have ZERO problems.

With 13.5" wide tires you will need to make sure your wheels have a little more offset or get wheel spacers. As Well as cranking your Torsion Keys to make some more room. You will still get some light rubbing but this wont cause any harm as it will be on your sway bar.

That is a solid answer.

I had 37x12.5 tires. The truck was fine. I then went to 37x13.5 and had to crank torsion keys to get them to fit. If you have no desire to lift it be sure to go with the 12.5" tires.

toyo MT 35 12.50 18 on 18 X 9 RS's. 37 12.50's would have been tight at stock height. 37's on the stock wheels work well (12.50 wide) at stock height. As soon as you go away from teh stock offset/ backspace, you'll have to do test fits.
The 18 X 9 has 5" backspace and worked well offroad.

37x13.5 inch tire without any issues? Meaning Would I lose top end on Highway ? What back spaces would help ?Its a
stock H2. no lift with no air ride .....If I go with 37x12.5 instead would I notice a difference in power like would she become a pig on a Hill going up ?

Thanks i looked aswell and have not found answers to all ?'s

37.5's stock is not going to work unless you pull out plastic. Because of the wheels, you are going to have rubbing too without spacers. You are goin to lose top end power too. Luckily, I have just gone through all of this just recently. I have to sell one set of rims and get a different set that had a bigger offset to not get the rub. Had to put in 2 inch lift (mainly for looks!) that helped the wheels clear to not pull plastic, and it has been in the shop for the last 2 weeks getting regeared because of the power problem, losing its punch. Had to do chip, looking to do exhaust and intake soon, and will most likely be looking to do supercharger if the regear doesn't please me. If you are pretty set on the 37.5's, do yourslef a favor and get a lift. You will not be disappointed!!
