OK, I've literally just fitted a set of 235/70/16 Insa Turbo Traction Track tyres to replace the standard 205/80/16 tyres it came with.
The car rides fine but I came onto some dual carriageway earlier and whilst I don't mind the 'aircraft' noise that chunky tyres tend to make, there was a significant rumble throughout the whole car, mostly from the rear I think. This was not apparent with the original tyres.
It didn't feel like the wheels were out of balance (it wasn't a 'wobble' as such), but there was a definite, distinctive rumble - one that you could hear and feel. It was very 'bassy' too. It started at 60mph and got louder/fiercer the faster I went, up to about 75mph when I stopped trying!
The weird thing is, when I let go of the accelerator completely, everything went quite. Barely any tyre noise, no rumbling/shaking, nothing. :doh:
So, are the new, bigger, grippier tyres at fault or are they highlighting a mechanical weakness somewhere in the drivetrain, rear diff maybe? Help!
Thanks guys (and gals).
