rolling radius

Is it possible to go swamper on 17’s and retain the correct rolling radius? I have 18” sportlines and considering the change to either swamper look or going 20”. I would like to keep the speedo and gearing as near as possible to standard. (102 remapped to 150 with 5sp manual box) Cheers

So am going down the At route with my fmo. Liking the look of the tristar concept which has 17" wheels and chunky tyres. Anyone know what tyres can go up to?

As quite many are using 20" wheels, which by the way do look rather nice, but it is not suitable for all users. So please be kind and show your 18's and 19's to help make up my mind and hopefully gather good visual database for other users as well :)

Hi, I was going to have the Seikel raised suspension kit fitted to my van which includes 235/65R17 108H tyres being fitted to my standard wheels, they tell me that if they do s speedo adjustment to match these tyres that there is a possibility that the cruise control will stop functioning...

Got standard 17" Devonport alloys and 150 bhp dsg box. I want to go for 18" probably sportlines as part of dropping it few mm too. Does the change in wheel size or tge rotating mass have any detrimental effect to performance of the dsg? I assume Speedo will return correct speed as...

hi all, does anyone have all terrain tyres on their van? I love the look but am interested in how loud they are compared to smoother tyres and if there are any other draw backs people have encountered, thanks

Afternoon all, Quick question. I am planning to put some 18" alloys on my van with 235/50 R18 tyres fitted. Will it still be ok to use the original supplied spare wheel with alloys of this size in the event of a puncture? Thanks

Hi peeps. Look I know everyone has an opinion on this. But I have my 20's on my T6, a few warned me about it screwing my gearbox, then others say no I wouldn't, we've been and done that now but to a mere fool that I am. Can anyone answer me why VW think big wheels do the gearbox in? Surely my...
