Shucks! One of my posts is missing! I thought I posted a few days ago about staggered E90 tyre pressure. After servicing my car on Monday at AB Segambut, I noticed they had pumped the pressure very high at 40 psi (front) and 42 psi (rear). I didn't like it at all and reverted back to 32-35. However, I discovered that the circumference of my tyres had grained quite a bit and wondered why. I discussed with E46F and he explained that at 32-35, my tyres were too deflated causing greater stress on the RFTs, at the edges. I think he's right on that. If so, how much pressure should I pump my tyres? E46F recommended I try 35-37 but that sounds a bit hard for the ride.
