The wider tracks would aquaplane easier in the rain but the wet weather properties in the F1 makes up for it. So far, nothing comes close to F1 when it comes to handling in the wet and I just love it when I leave my fellow friends in AD07 in a spray of water during rain.

When i try 34psi front & 32psi rear into my 14". Wah...damn good the response. But suffered a bit when raining.

i put 32 in front 35 for the back ..imo handles bit better
all tires @ 225/60/R16 .

195/55/15, 240/230, front/rear

mine is 32psi for front & 34psi for rear coz I am driving FR car.

True, true. Closest rivals would be the Proxess
Really regret opting for non-rotational Ziex

front 38psi
rear 34psi

205/50/R16 Bridgestone Potenza Adrenalin RE001.

actually, i've monitored and tested quite a few petrol station air pumps. and most of the time, they are around 2psi lower that stated. meaning, when u set 38psi at the pump, the actual pressure into ur tyre is 36psi.

i with a michellin tyre pressure gauge the moment i finish pumping at the station itself. some petrol stations even go as low as 3-4psi.

therefore, alot of tyres are actually under-inflate.

conclusion, just set the pump to be 2-3 psi higher than ur desired pressure.

hope this helps.

250kpa all round. The fat 65 series NCT5 works best without the sidewall flexing and hopping around in corners.

30 psi sounds low for a normal street-driven car, probably dragging the engine a bit too. u can try higher pressures bit by bit till u find a best compromise that makes the car lighter yet not too bumpy

is it ok to put more air into old tyres?

pump at workshop "dry air" instead of at petrol station "wet air" . "Dry air" will maintain the tyre pressure longer in comparison.

dude u sure? i only running on 33psi for both my front (245/40/18) and rear (265/35/18). Can it really take 40psi??

40 psi is still within the limits of most tyres, but the more you pump, the closer it is to this limit, and therefore there's less safety margin to work with if the tyre hits a big hole or object on the road. just my 2 cents

Which ever station I go, I always see 29psi on the machine. So, I guess majority used 29psi.

Max pressured as marked on the sidewall is 51psi. Still a big margin to go...

i pump 32psi for all 4 tyres... car no bouncy/bumpy at all...

is it safe to pump 60psi on donut spare tyres? feel like will blow for a small tyre...
last time i saw a bangladash labour pump a tire for his trolley, the inner tube blow...

There's still plenty to go on my tyre. 51psi is max. I'd rather hit a big hole with a tyre full of pressure as the sidewall and rim will take less damage. Tyre will not blow out unless it was already damaged.

Added on February 22, 2008, 2:41 pmWell.. my manual says pump to 60psi before use. On the sidewall fo the donut spare also says pump to 60psi before use.

Pressure = Force/Area

where F = weight of 1/4 of the car
A = contact patch

Since the contact patch is less than the normal tyre, but the weight is the same it does require a higher pressure to sustain. Itu tayar cakap 60 u letak 60 lah. That tyre is built for that kinda pressure anyway

Rim damage/tumours are more likely to happen with underinflated tyres. U can see what happens when an underinflated tyre is pressed against the kerb stone if u park the car too close..

okie... just i worry that i never pump 60psi for any tyres before...

i dont want get kill bcos over pump the tyre and explode in front of me. long time i heard a news from newspaper that some1 pump his CASE (construction vehicle) tyre and get kill bcos the explosion...

next time will pump it, more than 1 year not pump air on it...

215/45/R18
34 front
32 back
