TED DIMON Posted October 23, 2017 Report Share Posted October 23, 2017 I have 205/70R15"s on my 1969. I have no idea what the proper tire pressure should be for these tires. Currently I have 30psi cold in them as my best guess. Am I even close to the proper pressure? Any advice would be greatly appreciated! Link to comment Share on other sites More sharing options...
Gunslinger Posted October 24, 2017 Report Share Posted October 24, 2017 Look on the tire sidewalls...there should be information telling you the maximum cold air pressure. It could be 35, 44 or even over 50 psi depending on the brand. I keep air pressure towards the higher end for better tire wear but that also sacrifices a bit of ride quality. One additional bit of advice...I've found keeping 4psi less in the rear tires compared to the front helps handling due the the front weight bias of the Avanti.

However, I am reluctant to inflate any where near the maximum since this can quickly wear out the center treads. Therefore, I'll do 36psi in the front and 32psi in the rear and see if the ride is too rough and I'll watch for uneven wear. Has anyone found a better psi level for inflation?

Jolly-John Posted October 27, 2017 Report Share Posted October 27, 2017 Hi, Ted. I'm not an out and out "performance-type" Avanti owner. That said, I've had good luck with 32 p.s.i. all around. John Link to comment Share on other sites More sharing options...

If this has worked for you on your Avanti, then I'll try 32psi and see how it works. Thanks for your input! Link to comment Share on other sites More sharing options...
Mel Posted January 7, 2018 Report Share Posted January 7, 2018 From a LONG, LONG, LONG time Avanti owner, 32psi in front and 30 in the rear. That's what I've run for 6-7 years and have had good luck with handling and tire wear. Link to comment Share on other sites More sharing options...
TED DIMON Posted January 7, 2018 Author Report Share Posted January 7, 2018 Many thanks for all your good suggestions. I'll try the 32 front and 30 rear and see if there is a difference. All of my driving for now is strictly around town until I am sure the car is truly road worthy. There are still some things that have to be done mechanically.
