Now then. Yuo have to be patient here this might be just my imagination.
I had the tyres replaced today. Same size but Colway ATs. Originally I was just going to get two but saw the price (£37) and had the front ones replaced as well.
Before replacement I had two reasonable tyres on the front and two near bald ones on the back also different manufacturers front to back. The car ,boomed, loudly when turning on near full lock at low speeds and at 30mph in 4th it did the same seeming to struggle to accelerate. Now, with the new tyres, it doesn't seem to boom in either circumstance and will even pull from 25mph in 4th. The revs are the same so the tyres aren't smaller. If anything they are taller.
The theory is that the tyre diameter difference, front to back, was increasing the drive ratio difference, front to back, and causing a more pronounced drag through the VCU. Early days yet but hopefully I will confirm after a 170 mile trip tomorrow. If it is I'll be rotating tyres on a monthly basis from now on.
