So I upgraded my showes to some 35" Toyo AT II Extremes ( awesome tires btw!) and I noticed that I took a performance hit. Lost power ( seemingly), seemed to have lost an entire gear...and MPG of course. After some debate I decided and looking at post by others on these forums I decised to pull the trigger on a re-gear. It's been 2 weeks and I am really glad that I did. It feels like I have some power back, it's definatley a little peppier and I got my 5th gear back. Also possibly some MPG too. I no there is a lot of debate as to waether or not you need to re-gear after going to 35s ...but I am personally glad that I did and I do notice the difference.
