Tyre size help please

[reddave101]

Any advice would be greatly appreciated.. It's now that time again to change out my tyres especially the front. I know standard sizes are 110/70/17 front and 160/60/17 rear. I've got the rear sorted but my question is I've got a spare new 110/80/17 for the front which I bought for a different bike which was never fitted. Would this be ok to fit the front or would it be completely different??? Have tried searching but not getting anywhere with it and don't want to swap them over and find there's a big difference in every way or not even sit right. My bike is a 98 fazer 600.. Once again any help greatly appreciated..

you can go up by 10 its only the profile, wont make a huge difference to be honest, you will need to make sure it fits under the mudguard though, it may be tight.

Thanks. Will measure it up when I pick it up from storage..

We'll went to pick up my tyres and shockingly I got it wrong lol . The front tyre I've got is a 110/70/17( got a couple actually) was surprised.. It was the rear that was wrong. I've got a 170/60/17 and not stock 160/60/17. Took the plunge this afternoon anyway and changed them both and it fits with a little Fettling to the hugger as the tyre being slightly wider it was just about catching it. And to be honest I think it feels a bit better at the back end. Having jacked it up 55mm, it feels loose at the back when I don't have a top box attached so tend to always ride with it on even when not needed.. Put the bigger tyre on and it feels comfertable on the road with no top box and feels like it's got better traction..

rear tyre is the same profile just wider, will make a bigger difference on corners. 60 is the profile/height from rim to bottom of tyre.
going up in profile would do the same as changing sprockets, i always try get 10 more on the profile if i can, have had wider tyres they do feel like they have more grip on corners but that will be down to the width of them, the cornering will be a bit slower but feel smoother

To be honest it felt more confident taking the corners with the 10mm upgrade on the rear. It went round the corners a lot quicker than I normally would and it did feel a lot better.

The recommended rim size for the 170/60 and 160/60 is the same
As long as the clearance is ok to the chain guard or hugger which ever you have.
It will feel sightly different handling wise especially as it wears

The recommended rim size for the 110/80 is smaller than the 110/70, it is at the limit of fitment for the fazer rim size.
It will have a much bigger effect on the handling than the different rear and the speedo will read about 5 mph slower.
Not sure if it will clear the fender as it  will be about 11mm taller
