I recently purchased the R/T 20's that were on Ebay, and now looking at tires.

I am not sure about tire size. I have stock R/T suspension, and have no plans to lower, as it is my daily driver & Home Depot truck.

Currently, I am running Toyo Prox II 275/55/17's, and have no rubbing issues at all. I am considering a couple of different tire sizes. I would love to go up to a 275/45/20, but it is over 3/4" taller, so I am worried about rubbing.

Or, I can play it safe and go with a 275/40/20, and lose only a 1/4" of tire height.

What do the experts here think? Pics if you have them would be much appreciated.

Thanks for all of your input.

Chris

I appreciate the input on the tire brand. I have them on my SSR and have been pretty happy, but it only sees dry weather.

I was more looking for comments on the actual tire size, so post has been edited.

Thanks,

Chris

my truck is lowered with 3inch springs in the front and hotchkis leafs in rear, and i was running 275/45/20's with no rubbing in turning, but when i would go over a big bump i would scrub on the fender flares. 275/40's on the front now dont scrub hardly at all even on heavy bumps, but as far as turning, i havent had any problems out of either size. With you being on stock suspension with no plans to lower, and being a home depot and daily driver, i'd probably go ahead with the 275/45's and you wont have any problems

Much appreciated input, thank you. If I understand correctly, you had the 275/45/20's on 3 inch lowered suspension, which would be 2 inches lower than a R/T?

Thanks for your input. Correct me if I am wrong, but wasn't your stock height 1 inch higher on your Q/C than a stock height R/T? I am wondering if that 1 inch difference will cause rubbing.

Well I dont know much about R/Ts. Im still new to these Dakotas. But I did recently swap the 20s out for a 31x10.5x15 which is a little bigger than the 275/55/20 and that doesnt rub either.

I'm sooooo confused!! I do not want to make a $700 mistake on a tire purchase.

275/45/20 is way to big..when i had my R/T i was lowered 2" and when i went over bumps i hit..i broke my fender flares from hiting..i had to stop driving my truck untill i changed the tires..i went with 255/35/20..but a 255/40/20 would be your best tires size

OK, I think I have it figured out! Going to do 295/45/20's on the rear, and 275/40/20 on the front. What do you guys think?

295/45s are huge. 2.5" taller than a stock R/T tire. If you for some reason want 295s out back, 295/35 would be the way to go. You'd probably be lookin at $400+ a tire in that size.

If it were me, i'd just go with 255/40s. MAYBE 275/40s, they're about an inch taller.

i'd agree, id do the 255/40's and you'd keep the same overall diameter. the 275 40's look good as well and would only be about .7 inches bigger, so they'd work well too. For your truck uses being a dd, and if you're anything like me (i live in atlanta and drive in the city alot) then i'd go for the 275/40's to have a touch more sidewall and width, probably be a little more common size for the 20's as well, so should be fair priced

Yeah I think you guys are right. I was trying to cheap out & use the rear tires off of my SSR & only have to buy fronts for the R/T. 275/40/20 in a Toyo Prox STII is pretty reasonably priced; I have 275/55/17's in the same tire on the 17" R/T wheels now.

Thanks for all the help & quick responses!

Chris
