I will tell you right now,33's will work, and they have been done. Im running 32's and have enough gap for 33's. I have no rubbing whatsoever with room for more. Matter of fact, I will be running 33's next tire set. You will have to do some chopping on the plastic fender well covers and black box mod, that is all.
For the life of god, manual stock gears are terrible with 32's. I was shifting from 4th to 5th about a thousand times freeway driving. Under 60, there is no 5th gear. I had a rear end built by east coast gear supply with 4.30s.. perfect combo in my opinion. I have some geddy up now (as much as there can be with the camel speed 2.7l) and my gas mileage has leveled. I run on avg, 18mpg city, 21mpg freeway.
BTW: Heres my thread where I documented much of my heartbreaks and ups and downs. http://www.tacomaworld.com/forum/5-l...zing-5lug.html
I hope that it may help you. If you have any questions, please don't hesitate to PM me. Either way man, lift it and get rid of the grandma styling of the 5lugger! I couldn't be happier with my taco now!
