I was checking the tyre pressures on front tyres of Becky II when I discovered that the front tyres were seriously worn. Because I don't have any money buying new tyres wasn't an option but I had other options. Because I have 3 Acclaims and a spare set of wheels in the garage, I can just swap wheels over which have better tyres. The only problem is that all 3 cars have different size tryes. Becky has 155s, Blue has 165s, Becky II has 175s (with a 155 on the spare) and the spare set has 155s. What I ended up doing was picking the best 3 out of the spare set along with Becky II's spare wheel. I preapred the wheels by inflated them to 30psi, blackening the sidewalls with my tyre dressing spray (97p from the local Wilkinsons) and fitting the best 2 to the car with the other going into the boot in the spare wheel well. After that I got my torque wrench out and after looking up the figure I toruqed the wheel nuts up to 59 lb/ft (80 nm) as per the workshop manual. I now heve 155s on the front and 175s on the rear. This is not illegal and it certainly won't fail the MoT (which is due in 5 weeks!) I've since put quite a few miles on which included a stretch of dual carriageway where I got up to 70mph and all is well.
That's what I call a result!
