Apologies in advance for a newbie question, but I did a search and didn't quite see the answer:

I just got a RAM 1500 with the 3.7L, and I'm really impressed with the truck - drives great, looks great, I'm totally happy with it as-is. However, my son is itching to upgrade to the 22" SRT-10 wheels (his money, of course ).

My question is, how would these affect the handling, braking and acceleration? Won't the odometer and speedometer be screwed up, and if so is there any way to recalibrate them?

this guy just blew out his rear axle cause of bigger heavy tires and rims, so i would be weary about doing it. read the whole thread. important points were touched on.

 

Acceleration will be affected if nothing else because bigger tires will equal a higher final gear ratio....Speedo, it'll be off by a bit - this is a link to an online calculator that will help demonstrate the difference - http://www.1010tires.com/TireSizeCalculator.asp

As far as gearing goes, that can depend on what your truck came with. If say you had super low 4:56 then going with bigger tires (unless they are huge) would probably not take your final ratio lower than the default for stock which *should* (theory) be safe...
