Right:
at the mo i have 750/16 sats fitted to my road 90 (200 TDI with pump tweaked) i have no idea what Tbox is fitted but at a guess i think its a 1.61 ratio,
what id like to know is any input on what size of tyres to fit ??
235/85/16's would be the equiv to the 750s but it needs the pump tweaked to pull them & dont want to fit 235/70/16's & then find its under geared still as at the mo it runs out of cogs at 65 just touches 70,
BTW what size is 235/70/16 equiv to??
