I actually think the gearing will work better on a turbo'd TD42..... I constantly feel like I need a 6th gear and as Fanus mentioned, most of them are closer to a 34.5". I would love to test a set for a week and feel what the difference is.
Tire height 265 X 70 X 16 = 777.4 mm
285 X 75 X 16 = 833.9 mm
315 X 75 X 16 = 878.9 mm
Difference from stock to 315's = 101.5 mm and 13, 06%. This is effectively giving you 50 mm more ground clearance which is great.
But here comes the kicker............
Tire circumference 265 X 70 X16 = 2 442.27 mm
285 X 75 X 16 = 2 619.77 mm
315 X 75 X16 = 2 761.15 mm
Difference from stock to 315's = 318. 88 mm and 13.06 %
The difference between the stock 265's and the 285's is 7.27 %.
I think that your hairdryer is going to be doing a bit of overtime with the 315's at low revs.
I think Tony's 4.8 has 315's on so maybe we need to feed him beers one day while we quickly borrow his wheels and tyres for a test but am not sure of the profile as his are on 17".
The other thing with the 315's is that fuel consumption is guaranteed to head in the wrong direction by quite a bit.
