Goldenvodka 2nd Gear June 20, 2017 Share June 20, 2017 (edited) Dear all, I have just collected my new vehicle I am currently on 185/60R15 tyres. There are 3 types of tyre pressures for different needs. 1) 36 Front/ 32 Rear - For partial load 2) 32 Front/ 28 Rear - For partial load + Extra comfort 3) 36 Front/ 33 Rear - For Full load Currently I am using No:2 as I prefer comfort and usually I am the only 1 in the vehicle. I just wanted to enquire here if using extra comfort pressure will damage the vehicle or tyre in long run? If so I will be switching it back to NO:1 - Using higher PSI choice, vehicle tend to accelerate quicker but road noise is high - Using comfort setting, pick up seems to be sluggish but noise level went down by much Thanks!

Eyke Supercharged June 20, 2017 Share June 20, 2017 (edited) no, but u will wanna be more regular in maintaining that pressure else might easily go too low. also, the stated pressure is when tyres are cold, if u have to travel some distance/highway/hard braking before reaching air pump then u should +2 or 3 PSI to compensate.

Sunny Hypersonic June 20, 2017 Share June 20, 2017 i am a kayu driver, cant feel much difference if tyre pressures are not far off from "ideal" singapore roads are considerably smooth/flat. i just pump 260 front/rear when tyres are cold, 1~2 month , pump again (if not wrong, was told 250 front/260 rear...wth) just dont spend too much time at tyre pressure pump area. some made me waited so long have seen more kayu driver than me, tyre flat liao still continue driving (had given him gentle honk so he noticed) Link to post Share on other sites More sharing options...
flashbang Turbocharged June 21, 2017 Share June 21, 2017 No need too stiff la, 32/28 is not too bad. Drawback is slightly higher FC. Link to post Share on other sites More sharing options...
F355 Turbocharged June 21, 2017 Share June 21, 2017 Instead of the two recommended extremes why dont you just pump in between ; ie 34 Front 30 Rear . 1 Link to post Share on other sites More sharing options...
Ahbengdriver 6th Gear June 21, 2017 Share June 21, 2017 I pump front 255.58283899 KPA. Rear I pump 299.893828 KPA The tyre shop where I bot my MeeCheeLeyn PS4S say one. Not I say one hah....Tyre shop say one. Link to post Share on other sites More sharing options...

For changing tyres, if not possible to get the same load index, it should be higher, not lower. Lower would mean the max load is reduced.

I would suggest to go higher and not lower. Lower pressure = more contact (to road) = more heat generated and thus more wear/tear. Link to post Share on other sites More sharing options...

For my car, factory tyre is Continental SportContact 3 SSR with load index of 84. When i change to Michelin PSS, load index is 88 Both tyre same size at 205/45 17 Edited June 22, 2017 by Davidtch Link to post Share on other sites More sharing options...
