Doing it again I probably would have gone gray.

What size tires are on her truck now?

I also thought about going with the gray, just not to sure how it looks on my blue truck...

The maroon truck is the one I'm driving now, it's got the 20x8.5 4.75" bs old revision 338's that I was going to swap onto the black truck she's driving; I'm considering letting the old wheels go altogether, instead of trying to mix the new fronts/old rears. The tires are same size all around currently 245/50/20 which are a little taller than I think will work on the dropped black truck, although I've raised it up an inch since that pic was taken. The black truck is running 255/45/20 front, 295/45/20 rear.

I'm running these wheels in 20x8.5 with a 245/45 all around. Width is perfect, it doesn't look stretched or bulging over the wheel.

 

[someotherguy]

Right...I'm clear on what size to run up front, already using a 255/45/20 on an 8.5 wheel and works perfect with this drop. What I need is a tire size in similar height but a width correct for a 10" 338 out back.

Im gonna go with the 255/45 up front with a 295/40 out back.... Should look good.

That's the sizes I have on my Boss 338's. They have the same sidewall height. Other than rolling the fenders (which was done when the 275/60-15's were on it.) I had no fitment/clearance probs.

I cant seem to find these tires in those sizes, what brand tires do you have? I want to buy them and I want matching tires lol

 

[sewlow]

They are Toyo Proxes II. Not made anymore.
I wanted matching tires, too!

SUCKS!!! I want to find a set in that size

OK, the 295/45/20's are maybe .75" taller than 295/40/20, with the same expected section width...so I guess I'll just re-use them. They fit fine now but they're on 8.5" Centerlines with a 5.5" backspace. Practically new Toyo Proxes S/T so might as well make good use. Will need new fronts though as they're much older S/T's that are cracked all to hell with just a little bit of tread left, been on there forever. Can't even say how many miles are on them but they've held up well.

EDIT - done deal; I ordered the 20x8.5 5.24" bs 338's yesterday for the front, bit the bullet and ordered the 20x10 338's for the rear today - gonna re-use the 295/45/20 on those, and ordered new 255/45/20 Proxes ST2 for the front. (ST's discontinued; couldn't find any and if I did they'd probably be old. Think ST2's are discontinued now too but stock is still out there.) A chunk of change but they're gonna look sweet on that truck!
