I'd like to know what are the right pressures for the front and the back tires for a 2003 S Type R. Can't find a sticker on my car with the infos...

thanks

 

Don't know if this helps (there has been a little discussion about tyre pressures B4 on this site), but in my 2006 S-type 2.7D I've found 31lbs/sq"., or right on 2bar I think, all round seems a good compromize between comfort and economy. None of my tyres are wearing improperly by visual check.

The recommended pressure for over 100 MPH is 36 in the front, 38 in the rear. I forget what it is for normal driving, but I keep it at this pressure and the ride is a bit rougher but I feel safer.

At the recommended pressure for under 100MPH the tires actually look slightly sagging.

 

The Jaguar door jamb sticker says 35 lbs "cold" as recommended pressure. I use 35 lbs "warm" cause I occassionaly "fly". Oh by the way, today I murdered a purple 2010 Dodge Challenger R/T.

 

My similar age (built 2003, registered 2004) STR sticker shows front 28, rear 32.
Frankly the handling's poor at those, so put about 4 more in them and see what you think!

 

35 lbs. +/- 2 to 3 lbs sounds reasonable to me.

 

My 06 STR has a sticker on the driver's door post. It indicates 40 PSI Front and Rear which has been working great for me.

 

thanks guys

 

EDIT CORRECTION!! The actual recommended PSI for over 100 MPH is 36/38 front/rear respectively. Sorry about the misinformation. Just looked it up again today

 

Switching to the 3.0 series. During our heat waves here in SoCal, my tire pressures got to aroud 38-40 #. I sure enjoyed watching the instant gas mileage read in the mid to upper 30's on the freeways at around 65-70 mph. Even though they may not be spot on accurate, still felt good.

 

Yep, bumping up those pressures a bit will benefit you with better mpg and in some cases, longer treadwear lifespan....

 

I have a 2005 3.0 S-Type and I typically run 36 psi all around. Ride quality doesn't seem to be affected but the handling seems a bit crisper. It may improve gas mileage slightly but where I live traffic is the biggest variable.
