Hi, I’m need help with tires sizes.
I have a JKU Sahara 2017 with stock wheels (18”), 255/70R18 (31.5” or 32”), no lift, automatic, 3.21 gears, stock coil springs (17/57). This is my 3rd jeep (1987,2010,2017) and I don’t want to go over board like I did in the past. Also, It’s my DD and will do minimal off road like country roads (no rock).
My goal is to have nice tire size with a 2”-2.5” lift maximum. I was thinking of AEV 2” spacer lift with Toyo Open Country AT2 (LT or Xtreme) in 33” or 34” tires. I found a tire size calculator (tacomaworld.com) that I used to compare and convert different sizes in inches. I was interested in those 3 sizes:
275/70R18 = 33.1”
295/70R18 = 34.2”
285/75R18 = 34.8”
Today I saw some comments from Eddie about tires and I got confused. He was talking about 34” really being 33”, some 37” really being about 35”, 33” more like 32”....so that’s why I need help. AEV told me I can put max 34” with there 2” spacer lift...but what size would be a real 34”? I also have a Daystar 1.75” spacer lift in a box in my garage (4 x 1.75”)...so can I go up to 34” tires with that kit? And last, is 34” going to kill my 3.21 gears (I’m in Canada, flat city)?
Thanks a lot
