Get a progammer and you can reprogram your speedo based on tire size.

 

is there any added body roll?

 

Ok, the speedo will NOT be affected as long as you get a tire of EQUAL size. I believe that a stock tire/wheel is 265/70R17. If I'm right, then for a 20" wheel you'll need 265/55R20 tires. Any local tire shop can give you the information you need if you wanna go to a wider tire with a stock height.

 

you do realize if u go with the same size tire as the 17" that you will have maybe 1" of sidewall on the tire?? I believe stock 17" tires are somewhere just under 30" and the stock 20" tires are 32.3" put a 30" on a 20 and wont be much sidewall there making an even WORSE ride then the ****ty ride the stock ones have.

 

And that's true too, I'm just saying that if you don't change the overall diameter of the tire, you won't have to adjust the speedo. Didn't say the ride wouldn't suffer and I'm not trying to be an *******, I'm just clarifying, if you will. Sorry if I upset (pissed off) anyone.

 

nope didnt **** me off haha, just stated its highly unlikely many guys would go with such a small sidewall of a tire, ACTUALLY might be hard to find a tire like that, not to sure though

 

In reply to dirtydodge02 and nathanp you both are correct to an extent. First off alot of your computers today are self correcting/adjusting. That is why once you disconnect your batttery for an extended period of time your engine runs a little rough because the computer is doing a self diagnostic and reseting itself. So what does all this mean. 1. check with the stealership you may be able to go from 17's right to 20's and not need to get your pinion factor adjusted. 2. If you can't all you need to do is have your computer hooked up and they(stealership) will tell your computer what size wheel and tire you are running. Now think of it like this. Do you really think that the powers that be would have separate programs just for tire size? No they wouldnt. Example you can buy a identicle Ram 1500's 4x4 the only difference being one has 20's and the other has 17's. Now they both are running the same computer programing. So you should not have any issues going to 20's. I hope this helps I just wanted to clear the air.

I don't know if you plan on doing any sort of towing with heavy loads but the 20s will decrease your towing capacity. My brother-in-law had an '04 Ram and learned that his towing capacity was about 1000lbs less with his 20s than it would be if he had 17s.

 

anyone here wants to trade for my 17's for your 20's? let me know. thanks.

 

umm arent the srt-10 wheels 22's ???? just clarifying
