Need some help. I have put two sets of tires on this car. One was a set of Cooper and the other was a set of BF Goodrich. Both were "High Performance All Season" tires. I have noticed with both sets that when I put in the proper air pressure that is stated-30 front 33 rear, there is a noticeable "hopping" effect. Like it bounces. I have owned two Porsche's and never had an air pressure problem even when adding higher amounts.

What pressure do the most of use use in your 129 SL500"s.

Thanks
