Tyre size, profile and rim size. Is bigger better?

Personally I wouldn't go wider then a 110 but have put 120 wide on them before

Going wider wont make it handle any better

Cheers, thats what the bike is speced for so I guess Honda knew what they were doing.

My rim has 215 x 18 on it. I presumed that 215 was the rim width?

Nah won't be that, as you wouldn't be putting a 110 or 120 wide tyre on a rim 215 wide, would look horrendous, and handle even worse!

It is rim width ya bogan. Rims are measured in inches 215 is 2.15 inches bead to bead.

Now I get it! In my defense, that decimal point makes a big difference

Ive got Sport Demons in 110 x 80 rear and 100 x 90 front. It looks a bit unbalanced.

As spares I have 1 x 110 x 90 rear sport demon and 1 x 90 x 90 MT75.

All tyres are in great condition. Should I fit the 110 x 90 on the bike to match the front?

Does profile make a big difference?

And the big question, does a wider rear tyre grip better or does it just weigh more and slow the bike down?

1. Why would you fit a tyre to "match" the other tyre? Bikes may take the same tyre, usually, the tyres are different front and rear... you do know the numbers mean things right?

2. Yes, profile makes a difference... a car tyre wouldn't allow a bike to lean...

3. Yes, a wider tyre should grip better (all other factors remaining constant) because there is a bigger contact patch. Profile not changing, yes, a wider tyre can slow a bike down, but it's re changing direction not outright speed.

Im not flash enough for a turbo sticker.

But fitted the 110 x 90 which is wider than the 110 x 80. Seems good so far and sits much nicer at 100.

Im sure my neighbours didnt mind me doing that at 5.30 this morning.
