Are these 20x9 rims??

I believe these rims are 20x9 with a +50 offset but correct me if I am wrong. What is the largest tire I ran run on these rims? I am planning of getting a 6" lift here soon and hoping I can run with these rims for 35s before I upgrade my rims. Any info would be more than helpful.

 

The only thing throwing me off is the +50 but I have some 35x12.5 18 tires on my truck until my new set up but must wheels where 18x9 with 0 offset

 

On the back of 1 of the spokes on the rim it's stamped nothing bigger than 33".

 

You can run 12.50 wide, i did on stock wheels for years. black pearl tundra runs 37s 13.50 on stock rock warrior wheels and wheels the crap out of it

On a 6" lift the +50 will have your wheels and tires looking tall and skinny. You can run 35s on 3" lift. 37s with trimming as some are now doing

 

Also it will say somewhere back there if it’s an 8 or a 9. Plus the dealer should be able to tell you the size and offset.

 

back in the day we used a tape measure
