r8rs4lf Posted December 27, 2004 Report Share Posted December 27, 2004 Ever since I had my 22's installed, I've noticed a signifcant decrease in power. Also, it seems like my tranny isn't shifting like it used to. Have any of you experienced this as well? I know that the larger rims will do something to all of that, but it just seems a little much. I wish I would have weighed my rims and tires before installation. I do plan on installing a shift kit, servos, blah, blah, blah, and also supercharging it this coming year so it shouldn't be like this for long. I was just curious if any of you have felt the same thing? Late- Alex Link to comment Share on other sites More sharing options...
jboyd2004 Posted December 27, 2004 Report Share Posted December 27, 2004 I haven't noticed any difference in mine...shifting or power. I didn't change the overall height. From factory, I think the total height on wheels and tires is around 31.8". I put the 22s with 305/40R22 which gives a total height equal to the original factory height.

Wizard Posted December 27, 2004 Report Share Posted December 27, 2004 I also used 305/40/22, which is the exact diameter as the stock 20's. I never noticed any difference with the 22's, but mine only weighed 29 lbs a piece. Good luck finding out the problem. BTW: I did notice a substantial increase in power with the supercharger Wizard Link to comment Share on other sites More sharing options...

haulin79 Posted December 27, 2004 Report Share Posted December 27, 2004 As you already know, adding heavier wheels and tires (while keeping the same overall tire diameter) will decrease your acceleration and it will feel like you lost power. I forgot that rule of thumb but it went something like: Adding 10 pounds to each tire or wheel was equivalent to adding 3 times that total to your chassis in the quarter mile. So that would be 10 lbs x 4 tires x 3 = 120 pounds! It sure adds up. Link to comment Share on other sites More sharing options...
BigTsBadSS Posted December 27, 2004 Report Share Posted December 27, 2004 My truck felt a little slower at first but thats about it. Link to comment Share on other sites More sharing options...
Xero Posted December 27, 2004 Report Share Posted December 27, 2004 well thats cuase their is more rolling mass. if you were pushing a wheel around a shop for what ever reason. it takes more work (force X distance) to move the 23" wheel and tire compared to the 15" tires A cause the smaller wheel is liter and B cause of the decreased rolling mass. same applys to the engine. you lose around 10-15 horsepower if you put a big break kit on. so you can immagine what the increase youve felt is over your 20" stockers. nick Link to comment Share on other sites More sharing options...
SSplaytoy Posted December 27, 2004 Report Share Posted December 27, 2004 I felt a bit slower and I have a radix, but it is not that big of a deal. You shouldn't feel tranny problems because of your rims though. Link to comment Share on other sites More sharing options...
