Tire size for a 4" lift

[gmartin1215]

Hi
I have a 4" BDS lift on my 2009 Tahoe and will be shopping for tires soon.

I have Michelin Defender LTX M/S 2 in 285/70R/17 on 17x9 wheels. According to the spec on these tires they are supposed to have a height or diameter of 32.8" But using a level and a ruler, I measured 31.5". I really don't believe I have lost that much rubber over time (got them in 2019) and maybe put 20-30 k miles on them so thinking they were manufactured smaller than spec - tread depth is still good and has not reached the indicator yet. I can fit into my garage (barely, have an 1.5" to spare). But know if I go taller, I may have to sacrifice getting it in the garage

Anyway, I want to go with a taller tire and want to know how big I can go. I don't want to go wider.

With all of you who have a similar lift, what tire and tire size are you running?
Are you able to park in your garage? If so, what is your garage opening height?

Anyway, hope you all can give me some ideas to consider.

I just did 275/6/20 on factory wheels. I went with the Cooper Strongarm. Amazing ride

I think @Tozan runs 34 inch tires on his 4 inch lift and it looks good

I am running Goodyear Territory MT's now 315/70R17 they are about 34.5 tall and 10 in wide. Good tires in wet snow and sand. Low noise and smooth.


I was running 35's before they were 34.6 tall and 12 in wide. The narrower 315/70R17 give me better traction and slightly better MPG.

If you are going to run taller tires you will benefit from re-gearing it, or deal with slow acceleration and terrible MPG... I would recommend 3.73 and no more than 4.10s

Also if you go to 34's you might need to trim a few things to keep them from rubbing near full lock.
