Anybody running a 255/45/20 and 295/40/20 combo?

You don't mention if your truck is dropped or what wheels but here is my $0.02 worth.

I don't have exactly the same but... 72 C10 swb - Front 275/45/20 rear 275/60/20. The front is dropped about 4" and the rear dropped about 6". Wheels are 20X9 with a 4.75" backspace. The bed is tubbed. The only issue I have with this size is when going down the highway and hitting a dip, the right front tire will scrape a little. But the front springs are weak. With full wheel lock left to right, no scraping. Tires fit within the fenders. Fenders cover about 2" of the top of the tire front and rear.

Overall it looks pretty good but as always, there are improvements to be made, so I am starting a suspension rebuild. The front will be dropped 2" and the rear 3". If the measurements are correct, the fenders will be above the tires by 1" front and 2" rear.

I would post a couple pictures but I am computer challenged and my son is tied up.

Thanks for the response. Mine is dropped 3"/4.5" with TT2 17s now but I just ordered these wheels in 20x10 and 20x8.5. I like the 255/40 for the front but I just wonder how a 255/45 (slightly taller than the 255/40) tire would look with a 295/40/20 on the rear.

Those are some cool wheels...

It is always hard saying what would look good for someone else. Personally I like the tire to fill out a fender well. It is cool having a taller tire in the rear. And with the truck having about a 3" rake. But take into consideration that I was a teenager starting to work on cars in the late 60's. Having the rear end jacked up was the style.

Over the past 50 years tastes have certainly changed, so it is all about what you like. If your preference is having the tires about the same height, then I can respect that and bet it will be pretty cool. Here is a link to one of many tire size calculators - https://www.tacomaworld.com/tirecalc...0r20-255-45r20 With the 295's, looking from the rear, it will be a good amount of meat on the road. That never looks bad...

I do have to ask, with your wheels, do you know the back space? On my 9" wheels, there is a 4.75" backspace and the 275/60/20 fit in under the wheel well very close to the outside (<1"). On the front 275/45/20's that is also close but maybe about 1.5" For the rear, I would think that you would need at least a 5.75" back space, unless you want the tire to stick out past the fender.

Hope the pictures come across, think that I finally figured it out...

The new rear wheels will have 5.5" of backspace. I spent some time researching, and I'm pretty confident about that, so now if I can figure out my tires while I wait for the wheels to come in. You're right, it's all personal preference. I like a little more tire than some, not as much as others. Not everyone will agree. I may just have to take a chance and try it. I haven't found anyone with that combo yet, but I'll keep looking at pics and make up my mind eventually. I have a few weeks.

I'm running 255/40/20 and 295/40/20. 4/6 drop implemented with ECE springs/spindles up front and ECE blocks/springs/shocks/C-notch out back.

No issues at all. Some might say that the sidewall is too small on the front with mine. I like it though.

Hth,
