DannyP Posted July 3, 2012 Posted July 3, 2012 Sorry if this has been covered elsewhere but I can only find information regarding the original wheels. Can anyone tell me what the correct tyres pressures are for: Front: 235/35/19 Rear: 265/30/19 Thanks in advance Quote
Ekona Posted July 3, 2012 Posted July 3, 2012 Wheel size doesn't determine tyre pressure, the specific tyre brand and type do As a rule, start with 35psi all round and adjust to suit. Quote
Stew Posted July 3, 2012 Posted July 3, 2012 Absolutely agree with Ekona. Rears are the wrong size though! Should have a 35 profile. Quote
DannyP Posted July 3, 2012 Author Posted July 3, 2012 Are you sure? I thought that the profile size was the percentage of the tyre width. Therefore the correct tyre size should actually be a 275/30/19 on the rear, but that would put the ratio front to back out (tho I believe some people do run a 275/30/19). Of course though I could be completly wrong Quote
Neilp Posted July 4, 2012 Posted July 4, 2012 Should be 245/35/19 and 275/35/19. I ran 235/35/19 and 275/35/19 for a while with no issues. This size allows the rears to spin a little more before tcs kicks in. Your tcs will be going off its head as the rears will be spinning too fast in comparison to the front. Quote
DannyP Posted July 4, 2012 Author Posted July 4, 2012 I wonder why the previous owner put a 30% profile on the rear then. I've had no issues so far with this though? When the rears run out I'll probaly stick 275/35/19 on instead, the missus might not be so happy with it been a bit more tail happy though Btw how can you tell which size rims you have? (The width obviously!!) Does the j mean same as inches? I am now getting seriously confused Quote

(The width obviously!!) Does the j mean same as inches? I am now getting seriously confused I am sure the j indicates width of tyre. Mine are 11 at the rear and 10 and the front for example. Size of rim is found by measuring the diameter. I run 285/30/19 and 265/30/19 on my rims and have no issues. Quote
