31 to 33inch tires. do i have to regear my mk
31 to 33inch tires. do i have to regear my mk
hi guys. was reading the threads of body lifts and i'm thinking of adding 2 inches to accomodate 33 inch tires. my mk has a sd33t and has a stock 4.37 diff ratio. can my engine/clutch/transmission take the increase strain of the new tires? do i have to regear?

if yopu have the turbo model, you will have enough power to drive them without dramas, but, to retain factory gearing, you could install a set of 4.6 ring and pinions, so it will feel exactly the same as it did on 31" rubber,
you dont "HAVE" to change gearing, but it could be an option, if you feel you lost heaps of power, but i say i wouldnt worry bout it

to regain factoey gearing as per 31 tyre you would have to go 4.8's on an MK SD33T which has factory 4.3's
4.3's + 31 = factory gearing
33 + 4.6's = factory gearing
35 + 4.8's = factory gearing
I know someone who has a set of 4.8's for sale at the moment in Melbourne for an MK/MQ...

indeed, but he has 4.3's which were standard with his 31" rubber,
he said he got "33"" rubber now, se he would need 4.6 to retain factroy gearing................................

Just run the 35's with your 4.3's....
Plenty of people here have......
It would be no different than having 4.6's and running 38 Swamper which many people on here either have or do....
cheers
James
hi james,
here in the philipines. 35's are hard to come by. 33's are gainig popularity but thier still kinda expensive. so, i'll go for the 33's first. thanks for the help

mind you there are a few extra ponies under the tin lid and an extra cog in the box
the 35's & 4.3 ratio will work, look to update ya diff further down the track.

4.3s on 33's are ok
4.3s on 35s is mega stretching it....
MY GQ lost 50km per tank out of its around town range when i went form 31's to 33's and is slower too...... its only got 4.1s i think...
screwy
