Drifting tire psi

I have a stock 7 except for bolt ons (intake and exhaust) and im just wondering what you guys usually run in your tires front and rear for driftin...

Don't dog on me that my car isn't great, I just dont have the money to do what i want.

Tires are stock 185/70R14 front and rear

You do realize that the old prius uses 195/65R15 and the new ones run P215/45R17....

Stop drifting and save up for some decent wheels and tires. Normally I run higher psi to help create more smoke, (I run with 235-255 rear) but with that skinny of a tire you should run lower psi just to get some sort of traction.

it's kind of a gamble for you to run higher then what the tire is rated for in the rear. it's easier to make smoke with a higher tire pressure but you do sacrifice traction/grip. it becomes mucher harder to keep a consistent line if you can't achieve stability. I'd leave the rears at the rated pressure and the front you can play around with.

do you have camber plates? if you do make sure they're at full negative, FCs are understeer queens and your tiny front tires aren't gonna help you any with that. when i still ran a 205 up front i brought the front pressures down about 10psi from the rating and then added or subtracted psi from there after each run. make sure you don't take out more then 20 psi though, don't want your tires to roll out from under you lol. different tires will act differently though so keep that in mind too. 10 psi may be too much or they might grip just fine at normal psi.

test, adjust, test, adjust, test, adjust, test, adjust......... you'll find the sweet spot eventually.

I think the biggest issue is far from the tire pressure. Stock 4 lug FC..... open diff. You have to swap in a LSD or weld the stock open diff.

yeah sadly its all stock as far as suspension. i wanna weld my diff but im kinda leanin more towards finding an lsd because welding the one it has might make it too weak, and since i have stock springs and struts its hard to get smooth transitions and that could put too much stress on the diff.

thanks for the replies.

welded diff will be fine. you're not gonna break it until ~300whp. with stock tires, theres a lot less stress on it than if you were on big rubber w/ power.

Against the 100 foot pounds of torque thrown at it? Yes.

Depending on what tires/age you can overheat (and possibly detonate) your tires running them over the max tire pressure. Says on your sidewall, usually 44 psi. I would not recomend running higher than 40. You may be able to slide around parking lots and stuff, spin the car out and get a feel of loosing control. But you wont be able to control the car in awesome fast drifts. So from my semi-non professional oppinion, don't exceed 44 psi.

And oh, go ahead and weld your diff. If you break it I have another one you can have.

I make 176WHP with 235/50/R17 and a welded NA diff and the only thing i break is diff mounts, a lot of them. Trust me, your diff can handle your NA's 75 ft lb of torque. With such skinny tires you won't have enough traction anyway lol.

Thanks man. I'll get on welding that diff. And I'm lookin at getting suspension soon. I want the package on racing beat that consists of springs and front and rear sway bars for 480. What do you guys think?

For drifting? Fail. For anything else, they'll work great.

You need to decide what direction your heading with the car before you buy any suspension. If your going for more of a drift build don't EVER buy aftermarket sway bars, it'll just be a waste of money in the long run. And 250lb to 400lb springs or whatever RB lists them at are far too soft, drift cars like hard 6k,8k, 10k, 12k springs which you won't find in a shock/spring combo anywhere. Coilovers FTW. And with those kind of spring rates swaybars are more of a option IMO. I ditched my rear swaybar a long time ago and haven't looked back. And when i can afford the JTP knuckles the front will be long gone also.

Save it up for when something breaks. When, not if.

coilovers or springs? 189 sounds too good to be true.
