I've seen several postings about tires. But I would like to see GT owners weigh in on what they run with. FR recommends 90 PSI (front/back), so what's everybody really doing (and why?)
I have a 320ds, and I run at 90. Not sure why. I too have always been curious as to what others run at. I have 19.5 tires.
Me too. 90 psi 19 1/2" tires 2005 359t

I run 100 - 110 per tire mfg recomendation. When i had front end lined up tire store said tires did not have enough air in them. They said you always go by what is on the sidewall of the tire.

I had mine weighted and according to the tire chart I should be at 90 but I put in 95 to be on the safe side.

Weighing your RV and then using the charts for your tires is the only right way to do it. Over inflation can cause issues as well. The pressure on the sidewall is for the maximum load limit on the tires. Most Georgetowns don't weigh that much.
