TIRES FRONT

All right. I here all about the back tire what about the front. Can you go wider at the front and has anyone done and if so can you tell the diff. I ask this because I have a friend that has a Vulcon2000 and his front tire is almost as big as my back tire. just a thought
 
A wider front tire is gonna give you a slower steering response time, and is not as nimble. Gotta watch your clearances of the fender as well!
 
I second that! Quite a while ago I tried to fit a 120 on my stock wheel. I had plenty of clearence width wise but had problems with the overall diameter of the tire. I ended up baking the paint on the top of my fender as a result of the heat from rubbing. (oops!) Ya, can you say dangerous? Anyways, a good way to prevent that is to go to the tire manufacturer web sites and check the tire specs, (ie overall diameter) before you buy one. I know there's quite a few that make 110's that should be ok. I couldn't tell you now though because my stock wheel is long gone and I have a 17" rim now. (still having problems w/ the fender issue too.)
 
Hi guys,
just wondering what the go is with tyres that look like they have been put on backwards. I've seen a lot like this on ebay, and even through here. If the tread forms a "V" shape doesn't it make sense that it points down at the front of the tyre to cut through any surface water and push it out the sides of the tread? Yet i've seen plenty where the tread points up, this should have the opposite effect holding water in. Your thoughts and comments appreciated.

My Avons have the lines pointing up, almost forming an upside down V like Andy's. And they're installed following the arrow, so the tyre manufacturers must know something we don't.
 
:dancingfool: PLEASE TELL ME MINE ARE ON THE RIGHT DIRECTION ,I`VE NEVER CHECKED OR CHANGED ANY ON THE BIKES I HVE NOW EXEPT MY DIRT BIKE AND THEY RUN BOTH WAYS(THIS COULD BE VERY EMBARRASSING :banghead: ANDY
 
I can't see the directional arrow on the photos, but they probably are Andy. If they aren't then you could just change it and never tell anyone, ever :ignore:
 
By my research, I think the arrows of the tread are supposed to point down, the opposite direction to what is in the photo of the front tyre on the bike, panther.

It's wierd, and I think you are right, maybe it's some new urban myth about directional tires and their connection to Al-Quida or some crap like that.....Who knows???

The annoying thing about these pictures is that you can't see the directional arrow on them. It could just be a case of each manufacturer doing their own thing.[/img]
 
I'll take a photo of my Michelin Commanders tomorrow and try and get the direction arrow in shot, just to see what you all reckon.

I know on large, rear tractor tyres, the point of the arrow on the tread pattern always hits the ground first when rolling, but it's designed to compact the mud/soft dirt against the sides of a deep wheel rut for better pulling traction when ploughing.

...maybe they've used the same theory for directional tyres on car/motorbike tyres.

Not necessarily. Here's a (bad) picture of my Michelin front which (only just) shows the direction arrow

The lesson i've learnt is from personal experience with tyres that were on the wrong way, huge difference in handling in the wet. If the tread points towards direction of rotation and the tread is in good nick then speed can be maintened as if the road is dry. When the tyres were on backwards they held water, causing an aquaplaning effect (scary). Hmmm don't think i'll be buying any tyres that dont look right to me, regardless of the manufacturers way of thinking. :cool10:
 
I would imagine that tire manufacturers have done significant R&D to justify whatever tread pattern you see. Lawyers would love to file a suit against any one of them for offering a tire that was less then excellent in quality,and without tried and tested safety standards. But what do I know; I'm always more concerned with the style of a tire, rather then the specs..
