A friend of mine has just been to kwik Fit and had two continentals on the back end. The price included new valves.
When he checked they had not put new valves in. The price of the new valves was nearly ten pounds. When he rang up to question this they said that they had not had any stock because it is special valves for MH's. I have never heard this before is it bull ****.

I'm sure more knowledgable members will advise but both my c class and present pvc have steel valves which I believe is due to the higher pressures on motorhomes so yes the Kwik Fit staff may be correct.
 
Surprisingly I have had 3 sets of alloys 2 on Boxers and 1 on a VW T5 all had standard rubber valves on Factory fitted wheels all the dealers involved and 2 Tyre Depots recommended these were OK no need for high pressure valves.

They had no valves in stock but charged for them anyway.
 
I live opposite a kwik fit having been ripped off twice
With cheap service's I no longer use them
The service might be cheaper but both times had a bill off nearly £1000
Brakes bad discs bad springs bad tyres you name it
Having done all the work a so called new spring broke and ripped a new tyre to shreds

As the saying goes "There's nothing thicker than a kwik fit fitter"

Just changed mine to Michelin Agilis camping tyres 215/75/R16/113Q had 4 new tyres balancing and valves £560.The old ones were just short of 10yrs old thought it was time I changed them

There are generally 3 types of valves used on vans, which type to be used would depend on the pressures used in the tyres.
 
Slightly off topic. I am thinking of reducing my tire size from 215/70/C16 to 195/70/C16. Question is, Will it be illegal and would it effect the performance of the vehicle. I have been informed my MH will go a 3 to 4 miles slower, which I don't mind. The reson of down sizing is because the present tires keep making contact with the fenders when I take a sharp turn or if I even hit a pothole. Your views and advice would be greatly appreciated.
 
down sizing from 215 to 195 will make your wheels effectively smaller which means that every revolution will take you less far, you are in effect reducing the gearing which will as you pointed out make yor M/h slower but on the plus side it will also slightly improve acceleration and hill climbing ability.

It will also mean that your speedo will over read - it may say 30MPH when you are really only doing 27MPH - not a big problem - certainly not as big a problem as changing your tyre side from 195 to 215 would give when your speedo would under read.

The big problem will be in load, 215 tyres have a higher load rating than 195.
a 195 tyre typically has a load rating of 104 which gives a maximum loading of 900Kg per tyre
a 215 tyre typically has a load rating of 109 which gives a maximum loading of 1030Kg per tyre

depending on what you are driving this may mean that your 195 tyres might be illegal

Thank you Sir, Your comments and advice is much appreciated.
 
If your tyre is catching on the inside of the wheel arch and you are using the standard tyre size supplied by the chassis manufacturer i would look at your ride height!
if your front springs have settled then that can cause that problem, Most Motorhome run at close to maximum weight and it is often prudent to put heavier duty springs on to compensate,
the other possibilitie is the wheels have the wrong offset to them, are they the standard wheels? or have they been changed since the chassis was built, Going down a couple of sizes isn't a great idea!

How does reducing the width of a tyre make the circumference smaller ?

Haven't checked on calculator but you'd probably have to go to a 195/75/16, possibly a 195/80/16 to keep the circumference similar. The 75 and 80 are %'s off the width.

On a 215 70 tyre the height of the tyre is 70% of 215 (150mm)
on a 195 70 tyre the height of the tyre is 70% of 195 (136mm)


the steel (or alloy) wheel doesnt change but the hight of the wheel off the road and hence the rolling diameter does

my tires on my car are 205/60/16 . 205 is the width,60 is the profile ,16 is the rim size . reducing the width only lowers the rolling resistance of the tire ,reducing or increasing the profile will make the wheel either roll further or shorter for one revolution of the wheel increasing or lowering your total speed . changing the tire size ie the rim size means fitting different rims simple a that . you can fit seventeen inch rims to many cars but you must come down a profile size to keep your speedo correct ,ie 16inch 60 profile 17 inch needs a 55 profile .your van will have a manufacturers tire size ,you can increase the width ie 205 to 215 ,but you must not reduce the width . my alahmbra can be fitted with 195 60 16 as its the 110 engine ,but the higher output engine has to be fitted with the 205 width tire ,but must be fitted with the correct width rim as per the manufactures recommendation many people fit different width tires to there standard rim but its a mistake certain tire widths need different rim widths fitting bigger wider tires and rims to a car or van can put all the steering geometry and ride out from standard manufacturers settings not always a good thing to do ,as it can effect handling and braking ,plus put extra stresses and strains on bearings and joints , .tire sizes are also a mot check you must have the correct width tire fitted ,but you can increase the width you cannot decrease the width

I am experiencing great difficulty, in sourcing a new set of Michelin Agilis Camping tyres, 225/65 16R, that are NEW, that is manufactured this year 2017.

No one, so far, will guarantee that they will be brand new! Don't know what to do next. The current tyres are now about 12years old, still quite legal and servicable, but need replacing. Michelin, themselves are not heplful, and say that any newly supplied tyres, manufactured up to 5yrs ago, will be ok.

Am I the only one that asks if a new set will be of this years manufacture? or does everyone else just trust to luck?
