How to tell if you have Jag, AM or generic spec tyres?

[Aitch]

Another consideration is how worn is the other tyre that will be on the same rear axle if you fit one new tyre?

1.5mm wear = 10mm reduction in circumference.

So how might this affect the dynamics of the stability control, ABS, TPMS, electronic diff while your rear end is trying to do its own thing?

£500 might be the cheaper option.

My fronts have the ‘J’ designation, but on the rears all I can find in the same place is TM
Any idea to what this refers to?
(I was thinking Trademark....)
