Put four new wider tyres onto the Panda the other week so I thought I'd provide a 1,000 mile update :
The original tyres were Continental Eco Contact 15 x 165 and just sort of 30k they were below the legal limit. Interestingly for a front wheel drive car, it was the rear's that wore out first on the edges
I rotated them several times front to back, but they were still the same.
The wet weather grip on the original low rolling resistance tyres was very poor with masses of under steer
Continental don't do a wider size and Khumo don't do 15" , so I fitted middle of the range Hankook 15 x 175 tyres
Wet weather grip is now vastly improved with at least 50% less under steer and dry grip is now good enough to lift the inside rear wheel when Management is progressing around high speed corners
How ever there are two minus points, the tyres seem more noisy on concrete surfaces and the fuel consumption has dropped by about 5 mpg.
It was averaging 52 mpg around town, now it's 47 / 48 mpg and at 75mph it's dropped from around 66/67 mpg to 62/63 mpg
It'll be interesting to see how they wear compared to the Conti's, with the Conti's cost £67 each and the Hankooks just under £25 each
