AutoSleeper Broadway Tyre Pressures
I know this has been covered many times in other forums, but would be interested to hear first hand experiences of Broadway owners on this dedicated A-S forum.
The posted tyre pressures on the door pillar of my Broadway EL are Front 72.5 and Rear 79 psi. These pressures frighten the life out of me when pumping up the tyres (especially when they have a maximum pressure of 60 psi printed on the wall). I know the tyre wall also says it is acceptable to exceed 60 psi for 'camper' use, but even so ...!
Tyre safe publish a very good informative leaflet and I know that the only real way to determine the correct pressures is to have the vehicle weighed when fully laden and then refer to the Tyre Safe leaflet.
Out of interest, what tyre pressures are other Broadway users running at. Mine are currently at F 65 and R 75 which gives a comfortable ride, gives no sign of adverse tyre wera and does not cause the tyres to run hot.
in advance for any info from other users. Lets get this dedicated forum up and running guys.

Re: AutoSleeper Broadway Tyre Pressures
Our Windsor runs at 50lbf/in2 in the front and 68 in the rear with Airides on the rear suspension. Ok its on a Tranny with bigger engine but the body shell is more or less the same.
Your "pillar" pressures do seem high. Why not ring the tyre manufacturers help line, they will advise. Certainly Michelin and Continental both have assisted motorhomers with similar queries

Broadway Tyre pressures
I recently asked Continental what tyre pressures my Broadway should have (my front door pillar label states 72 front and 79 rear):
Thank you for your recent query.
Typically, the stated pressures are the maximum that the chassis would
require - not what the load that is being carried would actually need. As a
result, they tend to be much higher than actually required.
In order for me to advise you of pressures, I would need the following
information.
1) Tyre size and tread pattern (model name)
Continental Vanco Camper
2) Tyre service description (load/speed indices) This is expressed on the
tyre sidewall e.g. 109R, 109/107S etc
215/70 R15 CP 109R also on tyre max 69 psi but this can be exceeded to
5.5 bar
3) Individual axle weights
Van weight max 3500 kg, Front axle max 1850 kg, Rear Axle Max 2000 kg
4) Fitment configuration i.e. single or twin fitment on the rear axle.
Single tyre on rear
The pressures you require are as follows.
Front: 4.25bar - 62psi
Rear: 5.5bar - 80psi (This is the maximum pressure rating for this tyre in
order to carry a maximum load of 2060kg)

Re: AutoSleeper Broadway Tyre Pressures
Evening Haslar. The only way to get an accurate pressure figure is to weigh the vehicle and get your actual axle weights. Then ring your tyre manufacturer who will be more than happy to give you a more realistic figure.
I had this really useful advice on this site but cannot find the original advisor, Squip or Roli I think, sorry if wrong. I have done just that and Continental gave me much lower pressures for my Symbol. The pressure on the vehicles plates' and those Continental gave you are allowing for it to be loaded up to it's maximum axle weights. The only problem I had was finding a public weighbridge. I didn't fancy using a scrap yard scales.
This is the email I received from Continental(my pressures were 4.13 bar all round):
Hello Mr B,
Based on the 205/70 R15C 106/104R Vanco you pressures are:
Front axle (1420KG) - 3.25 bar
Rear Axle (1360Kg) - 3.0 bar

Broadway Tyre Pressures
Hi, Thanks very much for the advice. I guess it is the weighbridge solution next. I assume that there must be a range of tyre pressures for given axle weights i.e. if your axle weight increases how much much more does the pressure of the tyre need to increase? It would be useful if Continental or Michelin produced a leaflet showing pressure against weight (or is it not this simple?).
