Ideal Tire Pressure on STag 19 non RFT

dicostal · 03-06-2012, 09:18 AM

Hi, I have a set of staggered Continental DW 19 inch, 235 front and 265 rear.
What is the ideal PSI?
I think the recommended psi for the 18 RFT of 32/38 may not apply.
I know I bought a set of 18 snow tires and the shop set it to 32/38 and the car felt so unstable and outright dangerous to drive. After setting the psi to about 33psi all around it felt just right.

I tried searching, but could not find anything specific to this topic.
I was thinking about 34 front 38 rear to start....

thank you - Luigi

I ended up going with 36 fronts and 40 rears
I would really like to get a professional opinion on what you guys think.

thanks - Luigi

Sounds about right - I'd just check your manual, it should tell you what the ideal psi is for both front/rears.

I did look at the manual, but those suggestions are for RFT and I do not think they apply to non RFT.

Thanks

IIRC 38 all round? or 38f 40r

I've been doing 35 all around.

38 all around works on my car.

I am running a similar psi. thanks.
I am on 235 front a bit afraid to go to 245 front as I think it may affect turn response.

I'm at 40psi all around.
