I have a mate of mine who is always banging on about what tyres he puts on his car and how much of a difference tyre pressures make and blah blah, i thought he was just being a bit of a try hard to be honest! But i take it all back now!

I changed my previous tyres on my TL wagon from some bridgestone RE92 (standard fitment) tyres to some bridgestone ER92 turanza's. I took the car for a bit of a thrash both pre and post tyre change and blow me down i was amazed at the difference! And the RE92's wheren't even all that worn so it wasn't just a case of old stuffed tyres being replaced with new ones! It's not so much that the car has a huge amount of additional grip over the old tyres, but they just "feel" so much better! Its much easier to feel the edge of the tyres grip, the understeer is more predictable in the slower tighter stuff and the lift off oversteer is more predictable through the quicker stuff! Basically the car feels much nicer to drive and seems to have much better balance on the limit then before!

Then a couple of weeks later i was noticing that the car seemed to be moving around a little bit much, so i went and pushed the hot temperature tyre pressure up from 35 to 40 psi and yep bugger me the car was way more stable!

So basically i just wanted everyone to know that its not just race cars that respond to different tyre compounds and pressures and stuff! Your average TL magna station wagon does too! So go make sure you put a good quality set of boots on your car next time you get em changed and keep a close eye on your tyre pressures! No more buying the cheapest tyre and checking the pressures once a month for me!

oh and the difference between the two tyres in the wet? forget about it! different leagues...

tyres and tyre pressures make the world of difference.

they are the only thing that keeps your car in contact with the ground.

id previously had RE92's or BobJane Allrounders on my cars. $90~ tyre

i then bought a car which had Conitinetal ContactSport2 Tyres, they retail for about $500-600 per tyre.

OH what a difference. in a simply round about test you could reach incredible speeds without slippage.

I'm a firm believer in buying good tyres for my cars, as the tyre is the only thing between you and the road, and all acceleration, braking and cornering is done with the tyres.

I used to own a (modified) Datsun 1200 that was worth about $1000.....but I had $600 worth of tyres on it (Yokohama A509s).
I currently have Yokohama A539s on my Magna.

Cheers,
Martin.

yep i always try to have good tyres only on the car....the mrs drives it mostly and with bubba it is paramount to me to have good grip in all conditions. I got the kuhmos as a tyre and wheel package but aim to go with bridgestone again or yokos soon

It amazes me especially that people dont take into account tyre pressures. Big big big difference, check it every 3rd or so fill up at the servo.

It's probably worth pointing out that most tyre manufacturers have cheap and nasty tyres, and also have premium quality tyres, so just comparing brands isn't really valid - you need to look at specific tyre models.
Generally, you get what you pay for.

So what would the people here recommend as the ideal cold tyre pressure for the Bridgestone Turanza ER 30 (215/60R16) which are the stock on TF Sports?

Thanks

Mitsubishi would probably recommend 28 psi.

However, for better tyre wear and better handling, I'd recommend 36 psi.
You can go higher, but the ride will suffer, and you need to ensure you don't over-inflate the tyres, else you'll get excessive wear in the centre of the tyre.

You are right Mitsu states 29psi!

Tyre placard on my car states:
tyre 205/65/15 ; rim 15"x6" ;
tyre pressure up to three persons front: 30 , rear: 26 psi.
tyre pressure up to max. load front: 35 , rear: 35 psi
When I got VRX 17"x7" wheels with 225/50/17 tyres couldn't find info about pressure , but I was assuming it will be higher than for 205/65/15.
Went to Mitsubishi dealer and checked tyre placard on VRX and tyre pressure was exactly the same as for 15" wheel
