My van came with 18s on it. The tyres are not rated for extra load so I'd like to change them, and I'd like to put something a little bigger on if possible. They are 225 40R18 all round.

Here's a picture...


Is it possible the alloys are a little wide than 225? And Does anyone else have a tyre with a bigger circumference on 18s? Like a 225 45 or 225 50?

What is the load rate on those tyres? should be fairly high.. What load rateing were you hopeing for? Do you have a full camper or just a van?

225/45 x 18s on mine, better than the 40s I had.

Load rating of 95 should be Ok for an empty van, running these on my ex-aa kombi.

I'm running 245/45 x 18 on mine due to all the pot holes everywhere very happy with them and they are load rated.

Wicked. I'm sure the load rating should be alright for an empty van as they're nice tyres. I do occasionally fill the thing up with people though, and it's LWB.

Thanks for the advice all. I think I'll definitely go up to at least a set of 45s. Does anyone know if I can risk a set of 225/50 x 18?

My hope is that would add a slight improvement to the mpg, hopefully without too much extra strain on the engine and box?

With all respect, surely swapping to larger load rated tyres just to save a couple of mpg is false economy? :confused:

It will cost you a lot more to renew your tyres than you will save in fuel I'd imagine.

For improving ride comfort I can understand, but not fuel economy.

Ah yes. But I don't want to drive on tyres that aren't the correct load rating (if the van is full), so I want to change them either way.

Since I'm already changing them, I'd prefer to change them to something which will save a little money in the future and has the most comfortable ride without straining the gearbox and engine. That's not the reason I'm changing them, I just want to make sure I'm making the best choice since I'm shelling out the cash.

Looks good too. I guess it's safer to go for the tried and tested 225/45 18 size rather than go up to 50. Don't want to cause other problems.

ours came with 235/40 95W all budgets.

Fronts needed changing due to tread so I've put Kumho tyres on today and ordered replacements for the rear (only 2 in stock). For ref I paid £238 a pair at Protyre.

Rears have enough tread but are Fullrun. Nice looking tread pattern but checked for reviews today and they are nicknamed - Ditch-huggers!!

What about235/50's? I'm looking at putting some 18's on mine now as well and the tyres they come with are 235/50. What kind of wear are you getting from 18's? I read another post saying to stick with 16's for extended wear and better comfort?

Hi,

I had 235-50-18's on the front of mine and have changed to 225-45-18's as the rolling radius was so big the van had awful acceleration. On the plus side comfort was good but I was unable to lower much.

My fronts are 8x18 et 35, rears 9x18 255-45-18.

Hope this helps.


Mark :)

Apologies if this has been completely covered but Im about to shell out on some new tyres due to wear and could do with a bit more of a direct answer if anyone is completely in the know? Also where is a good and affordable place for tyres?

what I have - 50mm drop (heavy duty springs)

Wheels = RS8
Rim Width: 8J
Rim Diameter: 18
Offset: 35

current tyres =
front 225 40 R18
rear 235 40 r18

Is it wise to have different sizes for the front and rear?
Can I go up to 235 50 r18's on a 50mm drop or is that that too much? ( I really want the comfort. I have tried to calculate this on websites but to be honest I havent got much of a clue about it)

cheers for some direct advice on this people - appreciate it as it will save me much time and money

Im in exactly the same boat here - i was looking to sort some steels out due to the roads..

Im running 235/40/18 and the ride is pretty hard, also, the rims stick out and are very prone to getting scrapped!!

ive found out i can defo get away with 245/45/18 or 235/50/18

any idea which would be best for comfort, ride protection etc?

or can I get bigger?
