think of it this way, Toyota put 4.30's in the auto trucks stock, 5spds had 4.10sso if a manual truck with 33's needs 4.88's you need 5.29's with the auto no bigger than 33's though
No, there are alot of manaual rigs out there that run a 4.88 and 37" tire combination on daily drivers with out any problems. We are talking about a set of 33" tire here... running 5.29's is going to give the best power yes, but its not power that is necessary when the trade off is lower fuel economy. 4.88's will pull a hill easily in over drive (.7 ratio). But then thats just my thoughts http://www.intercotire.com/site63.phpThese guys say a 5.29 is the most you will need to use for a 36 inch tire and the most fuel economy on a 44 inch tire...
what rpms are my gears going to be changing at. I dont want to be redlining it.
I regeared my 86 auto with 4.88's, it does make a big difference since those big tires soak up power and that auto soaks up at least 15% of your hp over a stick which is 0%. My 86 was a turbo but I think the results will be the same. It definatly helps offroad too in the rocks and climbing hills and such, but nothing will help downhill except finding the wire for that electric torque converter and putting a switch on it so that it doesn't go into the stall mode. That was on my list of to-do's but I sold it before I tried it. If you find the wire you just have to be very careful if you shut it off, you'll blow the converter if you stop with it in the off position.
um yea but interco's site is assuming a v6 or v8
I guess I must be missing something then. Quote from the site ..."These calculations are assuming a manual transmission with a 1:1 ratio. If you drive an automatic your RPMs will be higher, and the opposite is true if you have overdrive (your RPMs will be lower)."My wifes rig is a stock v6 auto with 32's and I dont have to re-gear it at all, but if I did I wouldn't go lower that 4.56's wich would probably turn up to a 35" tire easily. So I see 4.88's in a 4cyl auto with 33's working out the best. But hey it's not my rig, just my thoughts.
I wouldn't know for shure about yours but I am shure that some v6 tyotas had the 4.56 gears stock. I think it was the sr5 models equiped with 31s stock. So I'm just wondering what gears your wifes runner has.
go with the 5.29, 5.29 and a auto and 33 u will be happy
