Hi Kat
good question..that deserves an answer.
I have been "playing" around with different pressures and while some sites recommend say 32
( for and 18 in) the tyre shops here say 35 or 36.

Even my Naza dealer said 36 while the sticker in the car says 32
I have a Porsche with 235s and 265 and websites recommend 32 and tyre shop here says 36

Hey everyone out there , why don you list your tyre pressures for all to see.

1) 525iT 235 /40/18 Firenzas crap tyres) .................31/32 psi

235/45/17

32 front

Yoko Advan Neova AD07 rocks! :yes!:

225/45/17 going for less than 600 a piece...

I agree the grip is good when the road is dry, But its a different story when the road is wet. I also find the tyres to be a bit noisy though.

Hi 830,
If you are talking about the Toyo T1Rs, then RM520 is a very reasonable price.....Great tires...

There is no tire in the world thats
1. great in dry
2. great in wet
3. quiet

and if it fulfills one or at most two criteria above, it will definitely fail the 4th...

4. cheap! (and lasts 4ever/as long as possible)

PS2 fulfills 1 and 2, but fails at 4.

Others choose various compromises among the 4 factors.

So, up to the driver the choose the best mix among the 4 that best suits.

Neova matches PS2 in 1, and comes close in 2. Both are noisy. But Neova costs me < 600, PS2 wud cost around 1k.

In conclusion, Neova rocks! :yes!:

p/s - btw, CSC2 is quieter. Price I last checked, RM800+ a piece. For the price difference, I've put the money I saved into soundproofing the car...

Im running 225/40/18 Goodyear F1 GSD3 and i have 36psi all round. A little hard for some but this is my preference for feel and also to protect my BBS wheels on our local crappy roads.
