These darn metric sizes

i'm lookin to get some 33" tires soon but i wanna keep my stock wheels (edge 15x7) because i like them and don't wanna spend the money on new wheels. i know it's possible to run a 33x12.5 on them but i would rather not for fear of nasty tread wear. on the other hand, the 33x10.5 just look too skinny in my opinion. so my question is: is there a metric sized tire that is close to 33" tall but would be safer to run on my 7" wide rims? i tried to figure it out but these metric sizes just confuse the hell out of me haha. thanks for the help guys

metric sizes aren't very common for truck tires on a 15 inch wheel once you get over 31X1050X15. but i believe a 33 is close to a 305 in metric sizes

33x10.5 or 32x11.5 will be your best bet if you want to avoid rubbing. Both can be run on stock wheels.

thanks for all the info guys. i think i'm leaning more toward the 33x10.5 as opposed to the 32x11.5 simply because i already have 31's on there. i was runnin the 31's stock then installed some spindles so i'm lookin for a larger tire. i just realized i failed to mention that and it's not in my sig haha. i think the 33's will fill the fenders just the right amount.

If you want inches diameter from a metric size, just multiply the two numbers in the first part of the the size (like 235 * 75) and divide them by 1270, then add your rim size.

For a 305/75-16 you would multiply 305 times 75 and divide the result by 1270, then add 16. That gives you the diameter in inches.

If you can remember the number 1270, you can always convert with a piece of paper if you need to.

i know i can, that's not the issue. i want to keep my stock rims which are 7" wide. the issue is running a 12.5" tire on a 7" rim. i know it's possible but i'm not sure how good it would be for the tire, so i'm lookin for other options.

Why not go with an 11.5" wide tire? I ran 32x11.5" on the stock 16x7's and it was a good combo. You can get a 33" that's 11.5" wide as well.

actually there finding out its not good to use anything bigger than a 31X1050X15 or a 265-75-16 on a seven inch wide wheel. We're not even allowed to install them at work anymore. The reason for this is people who were running 32's and 285's on seven inch wide wheels were having there tires seperate because the wheels aren't wide enough.

My Dunlop Mudrovers had separation issues but they're known for that. The Cooper STT's didn't give me an ounce of trouble on the stockers. Both were 32x11.5

Well 265/75/R16's which is roughly a 31.6

The Kumho M/T KL71 comes in a 32x11.5x15

I've been looking for tires myself and I seen a handful of brands with the 33x10.5 and 11.5 sizing. I can't remember which ones were for a 15" rim though. Go to Tirerack.com and put in the size you're looking for.
