I did a search to no avail...
My sidewalls got all tore up drifting at around 38-40 psi. From one picture it looked like I was rolling over on them. I had 255/40R18's and 285/40R18's, so there wall plenty of sidewall to abuse.
Is it commom to run 48-50 psi to avoid this? Should the fronts be significantly lower pressure than the rears?

Sounds pretty high to me, do you mean hot or cold pressure?

I would think that you would want maybe 30-35 cold in front and maybe 5-7 more psi cold in the rear, im no drifting pro, but it seems to work for me on the streets when i want a lil more oversteer.

what is the width on your 18s, i just run standard tire pressure but i stretch it a little so theres less sidewall flex.

are you FI? thats alot of tire for drifting otherwise.

That was hot temps. They started out around 33 fr. and 36 rr. cold.
I don't normally drift, but my old tires were ready be replaced so I gave them a good spanking. I'll probably run 245's or 255's on the back to drift on the OEM wheels. I'm not FI, but my old tire/wheel combo is for grip driving.
Good observation. It took a little work to get them sliding, and when they found traction again it was like the hand of God pressed down on my back bumper!

I take out my track rays wheel and put the OEM base model rims on there. 17" are cheaper. Instructor told us in drift school he uses 30-33 psi but to us students 35 front and 40 rear.

Puerto Rico. Most of you don't know what or where PR is so I'll give some geographics. Caribbean Sea area, the smallest Island of the bigger Antilles Archipelago, adjacent to the Dominican Republic.

Classes and clubs vary, this weekend we had the stunt drivers of Tokyo Drift giving lessons and $300 per day. The secong was free to learn and be there but could not participate. I took third in the overall battle. Posting pics when i get home.

do you know the names of the drivers, most of them are from out here so...
rhys, samuel, tanner, calvin?


I think most people know puerto rico is in the caribbean, but it doesnt have a lock on the city name san juan, thats why I asked where.

on a side note, both my parents are from cuba, and ive been to puerto rico for vaction. so I definitely know where its at.

Alright dude, so you definately got family here starting with me. The drifters were from LA and mexican born. The certified Formula D instructor was Casper by last name. I'll look the specific names in my certificate when I get home. BTW, Cuba rules, dude. Too bad that Castro ****** f*cker is still around. And with Raul, we may be worst. Friends of mine say he is a dumbass and that F Castro is dead because he would never relinquish his power in a sane state. Either that, or he is really f*cked up. Hope we see a free Cuba in a near future.

most likely it was your front tires having sidewall wear. this comes from understeer. it will go away after you stop the understeer.

I know this is an old thread, but I have something new to add.

I was at Formula D yesterday and Tanner Foust said that they run really low pressures on their Z in order to get the right amount of grip. He said they run 21psi cold. Granted they need a powerful car to do this, but there is some info straight from the source.

That's the cool thing about a new sport- you can actually talk to the players
What motor is Tanner running?
I have a drift practice this weekend at Arroyo Seco in New Mexico. There are 8 mounted used tires in my garage. It's going to be a good winter!
