Please don't take this the wrong way but I think you need to re-assess your plan to fit the fatest tyre! My advice is to keep the tyre standard OEM. It is quite likely you will completely mess the bikes handling up by fitting a non-standard tyre size.

If you seek maximum grip on tarmac then go for a specialist ROAD tyre. But be warned your bike will look very odd indeed to anyone with a trained eye!

If you're like the rest of us then you will want to fit an all round tyre which can be used on tarmac but also for the odd dirt track too. Don't forget the bike you have is an allrounder and although it performs very well in city traffic it's primarily designed to be ridden on all surfaces.

I have recently fitted MICHELIN SIRAC's to my XT6E. Michelin's website states that 130/90 17's can be fitted but I opted for the STANDARD 120/90 17's and I'm very impressed with them indeed. I understand that the METZ TOURANCE is the most widely used tyre for XT's in Europe right now though. I imagine these can easily be sourced in the States but perhaps someone nearer home will be able to give you better guidance?

Most of us fit tyres that are 70% Tarmac 30% Offroad and the above tyres would come into this category.

If you want to fit specialist road/tarmac tyres then perhaps you should look at getting another road orientated bike?

Good Luck and above all stay SAFE!
