Still looking for tire size on lowered 63

I asked a question earlier about what size wheels would be good for lowered truck without rubbing. ( what I really need to know is the tire size for transmission builder)
Sooooooooooo..........thanks for your patience

looking to put wider tires and bigger rims (I'm thinking 17 inch rims, but could be talked into 18s)
thanks again

Re: Still looking for tire size on lowered 63

I bought 17s for the front and found out there is not much of a selection in that size. There is a lot more sizes in a 18 wheel. I used 245/50-17 on a 8" wheel the front. I have 255/45-18 on a 9.5 wheel on the back. I would have been better off appearance wise with a 275/50-18 on the back. The 255/45-18 is to small.

A 28.5" to 28.9(stock) height. A no hassle 275 wide. Rim size of 18 making shopping for tires easy. But found a 275/55/17 but as for transmission don't see the tire selection an issue. 3.73 rear with 28-29" tire is the sweet spot.

A 255/50/18 at 28.04" tall or
A 255/55/18 at 29.04" tall for all 4 corners. And 10" wide

My rear gears are 3:42, is there any good tire simulators for our trucks out there? I have been looking on the web but they seem very limited.
I would like to see how the different size wheels and tires that fit would look.
(seems like I'm hearing 18 inch rim for sure.....correct?)

275/60/15 vs 295/45/18 if a fatter side wall stick with the 255s lots of tire calculators out there and other years wear same size tires.

thanks for the link, Can you please clarify (275/60/15 vs 295/45/18 if a fatter side wall stick with the 255s lots of tire calculators out there and other years wear same size tires)
Not sure what your saying about the 255s?

Re: Still looking for tire size on lowered 63

255 gives a good size all around. Can be ran front and rear so you can rotate. Also gives a fatter side wall look while maintaining a good height overall for rpms. But a 27-29 inch tire is what you want. That picture is what was and what is on my rear. I had hard time going from 15 short of 13.5" brakes had me looking big. The 17s were hard to find in a truck size not a car size 25-27"tire. 18s were same price and better size choice. LT ratings as well but my Nitto 555s are rated for over 2k per tire, for a 5k gvw truck.

I'm not going to be doing a lot of heavy hauling, so I'm guessing regular car tires would be fine. (dont want a noisy tire)

I'm thinking 285 45 18 for my rears and 255 50 18 for front. (what you guys think??)

Re: Still looking for tire size on lowered 63

It's all in the popular size. A 255/50/18 Nitto 420s is $175
Found Fusion at $110 and a low $145 for Nitto. From Google shopping. If a ZR P Zero yes 400+

Re: Still looking for tire size on lowered 63

Yes I am running a 295/45/18 Nitto 555 rear. But I am also rubbing a bit being so low. The American Racing Salt Flats are 9.5" wide with a 4.5" back space. Front is 245/45/18 on 8" not sure might be 8.5" on 4.5" back space. That's why I say stick with the 255s but if the fat of the tire is not into the bubble of the inner fenders the 295 will work. Had 275/60/15 as seen in picture no issues and a small 235/60/15 front and 225/70/15 same height as 245/45/18 for a month while 18s were being shipped.

When you say, rubbing the bubble of inner fender. Are you talking about the fender tub of the bed of truck? Plenty of clearance to the outside and to frame rails?
Thanks a again for the input

Re: Still looking for tire size on lowered 63

The inner tubs have an indentation that causes rubbing. The outside is fine. My rear is also is a 70 so is wider than stock.
