Best Grip, Cant Afford New Tyres........yet

[illusiVe]

hey guys, i have a R34 GTT and im runnin 255/40/17 on the rear, they are down to legal limit of grip left..

either way, what PSI should i use to get most grip on the touge in the dry until i can replace the tyres.

its just 1 final run i need to make.

also if its damp, suggestions?

Won't matter a bugger if it's dry.Tread only reduces grip in dry weather.That's why racers run slicks at every opportunity.If it's damp you'll get tail happy.If it pisses down wait until it stops.Keep fingers crossed,take bible,watch out for black cats.

Come to think of it can't you get some secondhand ones with decent tread to tide you over? Much safer for cops and wet weather.

no way i can get the grip i had 2 weeks ago runnin 40 psi

or better.. im tail happy in the dry now..

It still does matter if the road is dry.

Yes, tread depth only matters for the rain, but when tyres are that worn, they are old and hard and ahve no traction at all.

Illusive, I wouldn't be touging anythign with shit tyres. Just drive it like a grandma until you can afford new tyres.

It doesn't matter whether you run 20 psi, 30 psi or 40 psi. they'll be shit anyways.

kk, touge it up either way is my answer =)

tyres are soft as, only had em 2 months.

Lower pressures will increase your contact patch, but decrease the tyre's resistance to sidewall flex. So you're talking trade-offs.

What kind of tyres are they? If they are a sports tyre with reinforced sidewalls in the construction, you can afford to run lower pressures.

Not sure about Skylines, but I found with stock wheels on a 180sx about 30psi (in the rear) was the best for grip without sacrificing the handling much.
