question for you...

why on Trucks n Busses n stuff are the front wheels on the oposite way round to the back wheels? is the hubs cave out on the front and cave in on the back... is there a particular reason?

also are the identical? (ie you can swap the wheels around as long as you rate em 180degrees)

its one of those things i've always wondered... lol

Ginge !

what jim ya buying a bus next

to give a wider front track???

better steering for heavy loads maybe?

the wheels are all the same per vehicle and interchangeable front to rear.

there are, on a standard 2x4 axle setup, 2 axles and 6 wheels - 2 wheels on the front axle and 4 wheels on the rear axle, giving 3 wheels per side. Obviously this can change depending on the driveplan of the vehicle - such as a tipper wagon, which commnly has 2 front axles and 2 rear axles, thus giving a wheel plan of 4x8 (4 wheels driving and 8 wheel sets)

the actuall wheel itself can be mounted 2 ways - inwards or outwards.

the front wheels are mounted inwards, this is to cover the drum/disc that the wheel nuts secure the wheel to.

the rear wheels are mounted, the first one per side, inwards like the front, and the outer facing one outwards - this is to give better load dissipation over the rear where the load is most likely to be. Also, gives better traction in slippery conditions, altho once they slide they are like giant sledges

Also, the drive axle is the only axle you will normally find original tyres on, all other axles normally have remould or re-cut tyres cos HGV tyres are so damn expensive.

ALWAYS new tyres on the front axle. Remoulds go on the rear if anyones really interested

Jim Galbally

why's that mate?

rickslack

Oh my god, someones actually interested. New tyres less likely to have blowout as the casings are new and un-dammaged etc. Remoulds re-use old casings and basically stick new tread to them. Thats why you see large lumps of tread on the motorway when a back tyre blows out. If a rear blows at least you can still steer!

lol he does dont he

never knew that was the reason for them big lumps on the MW richslack, always wondered that!

I thought it was to cover disks at the front and drums at the rear...

Did know about fitting new tyres to the steering axel thou

Did you know that there are two types of HVG tyres (broadly speaking) one for axels that steer and one for axels that drive. It basically radial vs cross ply construction

used to put remoulds and recut tread tyres on the front of buses and coaches - never heard anything like that before - maybe the goodyear tyrefitter was a shosky fruit

I thought this was going to be another bizarre posting by Jim.

But it was actually informative and interesting.

Keep up the good work.
