Typical tyre width for the RV?

[scooby]

My RV currently has 205-width tyres on 16" Weller rims.

I managed to get a nice set of 17" alloys at a fair price on t'bay, so will be looking to tidy them up and hopefully fit wider tyres to them in the future.

Currently looking at either 235/70s or 245/65s, as these seem to be fairly common sizes so part-worns can be picked up for not too much. (I'd go for even higher profile, but they seem more rare).

Although the alloys have a smallish offset - ET 17 - I'll still need spacers to get them sitting where the current wheels are.

The car drives pretty well at the moment, with little bump-steer unless the road surface is really bad. Does anyone know how the wider tyres might affect this? Will it more obviously 'tram-line' for instance?

(Bearing in mind it'll very rarely go above 50-odd mph!)

Shouldn't be a problem I run 225/60-15 front and 255/60-15 rear but I do have bump steer bushes, I'm not sure if you could fit hem to good effect on the steering set up you have. Basically if your track rods bolt in from the bottom and have too sharp an up angle so it pushes the wheels out on bump you drill out the arms and fit tapered bushes to reverse the ball joint to fit from the top, levelling out the rods or in y case the reverse as I lowered the suspension.

Thanks Peter.

I should be fine, then, as the track rods are nigh-on level.

I guess what I'm experiencing on bumpy roads is a bit of chassis-shake?!
