I have Austone CSR71 195/70r/15c 104/102n 8pr load range D Tyres fitted.
All of my research points towards Commercial (Van) tyres.
I'm wrestling with what tyre pressures i should run? I've read 65psi which sounds high then a host of other suggestions on various forums.
Having never run commercial tyres before i'm looking for a bit of advice.
What would you do?

Re: Commercial tyres
Never heard of more than 40psi all round being used, but 70 is an unusually deep walled tyre on a Bongo so wouldnt know about those. Do they improve ground clearance much and how does the Bongo handle with them?Timandclaire wrote: ↑Fri Aug 30, 2019 9:51 am I have Austone CSR71 195/70r/15c 104/102n 8pr load range D Tyres fitted.

Re: Commercial tyres
They seem very good in every respect hence why i would like to get the best from them i.e correct tyre pressures when i bought the van they had 34psi a corner but looked low when fully loaded so i upped them to 36psi a corner i spoke to a tyre place this morning that recommended between 40 and 50 psi..
Confused would be an understatement!

Re: Commercial tyres
Thanks for that update. I guess one strategy would be to settle on a given tyre pressure and watch tread wear - if its more in the middle it'd suggest pressure too high. As long as tyre walls look ok at ground contact area (and unless there's firm evidence this tyre size needs a higher pressure) I'd start at the lower end (40 psi) and see how you get on. Higher pressure = harsher ride so best starting at the low end i reckonTimandclaire wrote: ↑Fri Aug 30, 2019 11:01 am They seem very good in every respect hence why i would like to get the best from them i.e correct tyre pressures when i bought the van they had 34psi a corner but looked low when fully loaded so i upped them to 36psi a corner i spoke to a tyre place this morning that recommended between 40 and 50 psi..

Re: Commercial tyres
I tried 40 rear and 38 front this weekend..i noticed that the max load rating on the tyre wall is quoted at 65psi!
