Tire Size and Load Index

**Bloomer89** · 12-28-2016

I am looking to move to a 35" tire on 20" rim but have a question regarding load rating. Should I have any concerns regarding the tire load index not exceeding my GAWR (6000lb according to the drivers door/6500lb according to Dodge site) - assuming I maintain E rating for tire. I am finding there are very few tires out there in a 35" that are rated above 6500lb combined (for the rear axle), but quite a few that are 121 load rating, which implies ~6400lb combined. With tires as the limiting factor, I would think it is safe to run a 121 load index tire as long as my load does not exceed that load index (ex. 3200lb/tire)

Thanks and apologies if it is a redundant question.

I'd go by the numbers on the door, not the website

Bloomer89, Any E load/10ply tire would be plenty! They now offer an "F" load tire as well. Which you'd have to fill a quote form out for! (Customoffsets.com/quote) Or check these out: http://bit.ly/2hxqYkn Max Load Pressure: 3640@65
