I have the Sahara and was thinking about going a little larger on the tires.
Has anyone gone up a size to 33s? Did it have a negative effect on battery range? If so, how much? Also, what would the corresponding metric sizes be? Thanks in advance.

No problem. A lot of members have done it. Still waiting for my 4xe, but I already have my Rubicon take offs, in 33in. Looks like there is a very slightly effect on range, since the tires are heavier LTs and the tread is more agressive. Around 5-10% from what I've read. YMMV, P-rated 32.6" like some 285/70R17 will be less affected than 33.0" heavy LT tires like 275/60R20 E-load ones !

Anything that affects fuel economy affects electric range. So lift kits, bigger tires, rougher treads, extra weight, etc. will all have an effect.

I have seen no noticeable effects - running Rubicon takeoffs - I am sure in theory there is a difference with the increased rolling resistance but nothing I have been able to measure at this point. (1K miles with stock tires and now 2.3K with these)

Haven't gone on any longer road trips to measure the difference. Did go for a smaller trip this weekend and it seemed to have a small impact on MPG, but it's hard to tell on a limited drive.

33 is the standard Rubicon Tire size
