Tyre Size

Recommended Posts

Having collected our (1st ever) van (2005 used) I found that the promised spare wheel was not fitted.

 

After a week and a half of phone calls I was able to go and collect the wheel today. No problems, until I get home and find that the van is fitted with 175's the new spare is 165. (Yes I realise now I should have know the size beofre I went, but that's a novice for you!)

 

What are implications of using this 165 in an emergnecy? We are making our 1st trip next weekend but I'm unlikely to be albe to get back to dealer (60 miles from home) in the week.

Based on tyre saver wheel on cars (my 350 BHP Volvo had a tiny one) that are thin and even a smaller diameter I'd say no more than 40MPH for 40 miles would be OK (Well I would do it in a jam) but not very clever from the dealer! Ah Britain, land of rip off prices and poor service :rolleyes:

You don't give the full tyre size so I cannot tell you the difference in diameter but its not going to be a lot and only half of that matters!?

What is much more important though is the weight carrying capacity of the smaller tyre, as long as it is more than half the vans weight you will be ok but you need to be sure. The load index number is the number after the tyre size followed in turn by a letter which is the speed index.

What are the implications of using a 165 tyre on one caravan wheel and a 175 on the other?

I agree with the comments above, and in principle your 165 "spare" would probably get you home safely, BUT I WOULD NOT RECOMMEND IT. Sorry for shouting, but if the worst should happen, and you were involved in an accident, I'm sure that your insurance company would take a dim view of the practice. Indeed they may even have a "get out clause" that would mean you were not covered!

 

Assuming that both the caravan and the spare wheel were supplied by the same dealer, my advice is to take the 165 wheel and tyre back at the earliest opportunity, and insist on the correct spare for your caravan being supplied. In the meantime, should you get a puncture, personally I would call out a rescue service.

I took the advise and got back in touch and asked for the correct size tyre. No problem said the service department and the day before our first trip went to pick it up.

 

When I got home I thought I'd better check it out in every detail and surprise surprise: it was not the same weight rating as the tyres on the van.

 

I put this in writing to the service department by email and phoned to confirm the next day.

 

Next weekend I make my 3rd trip to collect a spare wheel & tyre, but now I know to confirm every tiny detail and dont assume that a franchised dealer knows best!.

Its amazing that people fall over on the basics. After your first problem, i'm suprised there not running to you after getting it wrong again.

We have a problem with older vans that were fitted with 13" tyres & rims. All new vans for a good few years now are fitted with 14's. The problem being that it is very difficult to find 13's with a load rating of around 460kg. Commericial tyres and those with reinforced side wall range from 14 - 16".

Running after us. . nahhhhh

 

I think the root cause is that by using such a large dealer we ended up in a situation whereby no one ever took ownership of us.

 

Aggree deal with salesman

Sort deposi with business manager

Deal with dispatch people on day of collection.

Ring dispatch with problem - reffered to salesman

Salesman needs to discuss with workshop

Salesman never rings back as promised

Sales man then passes to aftercare / service dept.

Service dept get it wrong twice but they probably see me as a complainer rather than a customer who had just spent a substantial sum with the Company.

 

 

 

A pity realy, as we found the van there that we realy liked, got a price we were happy with but now the edge has been taken off the whole experiece.

 

At least every thing worked when we got the van home, so no need for return visits for rectification.

Made the 3rd trip to the dealer last weeked and finaly now have the correct spare tyre.

 

The final part of this long sad saga was to have to wait for nearly an hour and a half while they actually found the tyre in the store and then to cap it all the fitter assigned to change the tyre asked quite glibly " what the socre here then, that one ( the "under-rated" incorrect tyre) would be ok!" with ut having any idea of what caravan it would be fitted to.

 

Lets hope he does not adopt that attitude when he's re-tourqing wheels!

Don't hold your breath!

 

Still, I'm glad you're now sorted.
