Is it a safe assumption that we stick with the manufacturers recommended tire pressure for summer tires? I just bought some 18 Kuhmos MX summer (staggered) tires for my 2005 E320 and would appreciate any feedback or tips. Thanks

what were ur original tire sizes and what psi? kuhmo ecsta mx max is 51 psi... 40 psi is really as high as u want to go for most circumstances... stuffed tires tend to give hard rides...but provide adequate load rating up to a certain point...
