[MRSPIKEPUMA]

I've recently bought some 17" alloys and tyres of Winnie (Great broke to do business with by the way). I was wondering what the correct tyre pressure should be. The tyres are

Yokohama A539 205/40R/17 84V on 17" TW alloys

Its seems the pressure on low profile tyres needs to be higher then the normal Puma tyres but I can't seem to find what they should be? Winnie had them running at 36lbs/psi but he didn't know if this was the correct pressure or not. I've tried searching the site and the web but can't seem to find a definate answer anywhere.

If anybody knows or knows or to calculated it would be most appreciated. Also if anybody is running 17" low profile tyres I would be interested to konw what you are running yours at, many thanks.

I've been wondering this myself since I got my 17s. Anybody care to enlighten us?

I'm running with 29 psi in the front and 28 psi in the rear.

As working in a rim and tyre shop I would recomend as much as 2.5-3.0bar(36-43psi) AS this will make the tires "job" of "protection" the rim much easier... We sell mostly 17"-20" rims (wheelie.no) and see damages of underinflated tyres all the time.

36-43psi :shock: :shock: rather you than me mate.

Maybe I calculated the bar-psi wrong but tell me whats wrong with filling 2,5-3,0 bar then? Some tires even needs 7-8 bars to go out on the rim....

Its the PSI pressure that I was referring to.

I think about 29-31 would be about right. The FRP's 17's are supposed to be 29 all round btw if that helps. :wink:

I always run 30's all round, when I had some new tires fitted, they blew them u pto 36/7 psi and it felt like I was driving a boat, dont go that high.

Well one bump in the road with to little pressure and you are looking and spending ?60 in repairs on the rim.........

I checked with our technical dept and they recommend the MAnufacturers pressures. When we work on OE projects with the MFrs we try all pressures. Do not be tempted to overinflate under any circumstances!!! the recommendations are there for handling grip mileage and safety, overinflation can cause accidents, wheels are cheaper than funerals!
