Welcome back.

 

I would go 5.13's for 35" tires. You might have highway regret with 5.38's

 

What about with 37" tires I have the gears and all the tools to install 5.38 but I kind of like how it drives with 4:10's on the highway with reprogram and cool air intake not bad with the power. Still find myself driving with the OD off lot on the highway and in 2nd gear too streets.

 

Thank you

 

Sixty, Well - I know there are literally hundreds if not thousands of posts on this subject but I based my decision on the following: (its an auto with the 3.8)
- 90% of my driving is from 0-50 mph
- When I'm on the highway I don't go above 70
- According to charts I have read it looks like at 70mph with 35's and 5.38's I would be turning right about 2500 rpm
looks like the 5.38's would be turning about 120 rpm more at 70 than the 5.13's so that would put the 5.13's around 2380 rpm
I then looked at the hp/torque curves of the 3.8 and they both are steadily rising at 2500. I was thinking since my usage is so much more off road/slower speeds I would go with the 5.38's
Based upon the above do you think I'm making the right decision?
Thanks!

 

Man, that's great. It's nice to love a vehicle enough that you'd "buy" the same exact one twice. Years ago a had a '95 BMW M3 that I loved as just a toy vehicle. I sold it to someone and told them if they ever went to sell the vehicle to please give me a show first. I contact them maybe 4 years later to inquire if they had any interest selling it back to me.......and he had sold it
