Default F4i feels a bit (loose) on the highway

Well besides discovering 2 small nails/staples in my rear tire (now need a new rear tire). Anytime i'm riding on the highway probably around 80mph or so, the bike tends to feel "loose" like it wanders a bit. My assumption would be because the tire wore out a bit weird (probably because of the low tire pressure i had in there and din't know about for probably a month).

Anyone have any ideas what i should check or anything? It didn't feel like this when i first started riding it so thats where my tire assumption came from.

The front and rear are both lowered which could be another problem, so any insight would be great.

Appreciate the help
Vic

I'd say no on this.

But when the rear tire was put on, maybe it was put on a little cockeyed. Could the front bearings be worn or loose?

Well the front tire feels great and holds air great. It feels to me like it really is coming from the rear.

I know on a car you can get tire pull so i'm thinking possibly because it wore out (low tire pressure) that it may feel wobbly?

How can i check my front bearings though? I checked my swingarm bearings (sorta) and everything feels tight back there. Even checked the rear axle bolts and there tight and torqued.

Oh and how could the rear tire be put on cocked?

by cupped, i don't mean that the front tire isn't holding air, i mean that it's getting out of round...like if you feel the tire, it has 'bumps'...like a monkey came and beat it up and it's all bruised up.

rear tire can be put on crooked if during install, the little bolts that help align the rear axle are not turned out or in the same number of turns.

Are you sure that you're not just feeling the normal variations in tire grooves and crests in the roads?I commute on afreeway every day and I'm constantly suprised by the variations in the road surface which cause "drifting"
