Tyre Pressures

[DjeMz]

shit just got personal, no one calls me a typo and gets away with it, no one...

but but... im ur lover???

i soo gotta change my tire pressure tonight... 45psi rears + 2 way = fun

wat tire pressures should i run on the front (90% dori)?

i have selby/whiteline sway bars... rear set to hard front set to soft.. rear cradel bushes set to 'overall performance'

depends on the tyre and rim, i run around 30 front and rear for drift, people often run higher psi at the rear thinking it will last longer, but it actually delams the tyre quicker. but it comes down to just having to test, go out, have a feel, play around with psi and try again.

17x8 225s stretched

i just run ~40psi for less sidewall flex... especially on on higher profile tires... if the profile is around 40 i leave it on ~35-37psi

lol, 225's aint a stretch on a 8", with road tyres its gonna flop around a bit, id probably be running around 35psi, but thats just me, i hate the feeling of the front tyres gliding over the road and not grabbing even if it means the sidewalls arent as rigid, saying that i dont run crappy street tyres on the front so i usually dont have that problem. get some decent performance tyres with rigid sidewalls, best of both worlds.

sorry i meant 215s.

what are u running on fronts

[nisskid]

i run 225/45 RE070's on 17x8.5 or 235/45 on 17x9. some say its too much grip for the front end and it unbalances the car having tyres like that, but i like it.

Should make this a sticky of some sort... condensing all the info in here... very useful for a newb like me...

im assuming you are all just running air in your tyres?

i have nitrogen in my tyres, which is not supposed to expand as the tyre gets hotter

so i have my tyres set at 38 when cold (234/45/17)

just for street use.. i find it really good because when ever i check my tyre pressure it never changes.

most tyre shops charge about $5 a tyre to fill them with nitrogen

Heat any gas, liquid or solid and it expands. Just at different rates

Nitrogen still expands with heat, let's face it air is ~60% Nitrogen. The big advantage is the lack of humidity, the water (H2O) splits into H and O and that increases the expansion in the tyre. Dehumidified air doesn't expand much more than 100% nitrogen.

Just after some input

I have FEDERAL EVO 595 SS tires on my R33 GTR wheels which are 17 x 9 - I'm running 215/45/R17 tires

I have had both front wheels balanced but it vibrates a fair bit, then I dropped the tire pressure from 34 to 30psi and its quiet a lot better

I realise some of the vibrating issues may be due to the stretch of the tires on the rim but what would be a good pressure to run these wheels at?

What pressures should I be running on my tyres?

I drive the ER34 enthusiastly everyday.

Yokohama Advan AD07

Front : 225/40/18

Rear : 255/35/18

Many thanks.

I run about 40psi front and rear in my 235/45r17's. But I also do a lot of highway driving.

I find that if you keep an eye on your tyre wear you will be able to tell if the pressures you are running are too high or low. Then you can simply alter it accordingly.

However if its purely grip that you want then all of this probably wont help you lol. I'm just more interested in tyre life as I don't drive like I'm on a race track all the time!
