Hi all just saying hello and getting used to this.I have not long recently purchased a freelander td4 and today noticed the back tyre looked flat.I checked the pressure and it was 15 while the rest was 40 so getting repaired the morra.but what is the correct pressure for 215/65r16?i also have a noise from the rear,the lad did say it would need a new bearing in a few month and I didn't hear it on test drive but it seems to be getting louder?could it just be worse if the tyres are over inflated?tyres are all new (open country).thanks,any help appriciated
