Sorry for all the posts, I just have lots of questions.. Well I know people always ask about rim size and weight and the turning radius, ect. Well if a rim is lighter it is going to take less power to turn, right? Then people start talking about how a 17 inch still takes my power becuase the turning radius is greater right. Well what about the freakin tire. You have to add the height of the tire too. So what if you got a 17 with low profiles. Couldn't you get like the same turning radius or lower. Also you can get 17 inch rims much wider which means wider tire, that means more rubber on the concrete. Have you seen a Vipers tires their like a over a foot wide.

 

What exactly are you going to be doing that you need to have an exact turnressure/lb. ratio? To be honest bro, I've had the stock 15's, 17's, 18's, and 20's on my car, and the ONLY rim that I noticed a significant difference in the amount of power that I needed to exert in order to turn the wheel was with the 20's. You probably won't even notice any difference between turning a 15" rim and 17" rim, or even a difference between a 17 and 18 inch rim.

I'd say go with whatever wheel you like more, and don't let the turn radius factor into your decision too much!

 

I am talking about drag racing... Where everything counts to get the fastest time, not just rolling around the neighborhood on your bling bling 20's...

 

That's what I thought you were talking about. I figured that drag racing implied racing down a track, in a straight line, so the turning radius of your tires wouldn't really be a huge factor. What's wrong with a little bling bling? (I sold the rims over a year ago, i'm back on stock 15's, but I'm waiting to put the 19" axis's on)
