Are the tyres correct size?

[Casper85]

Hi guys,

I've recently purchase a 2nd (or possible 3rd, 4th etc judging by their condition!) hand set of the 19" VXR Ronal alloys.

The fact they will need refurbing doesn't bother me, I paid £250 for the set so probably the same outlay on refurbing meaning still cheaper than most sets I came across with cracked alloys!

What I am puzzled about though is as to why they have different sized tyres on them??

Two have 235/35Z/R19 91W tyres and the other two have 225/35Z/R19 88W XL tyres

Is this naturally correct or has someone fitted the wrong size to two of them??
I bought them to go on my Vectra C SRi which currently has 17" standard alloys on.
Years ago I had 19" Snowflake Alloys on (regrettable had to sell them on to raise some cash) and I'm sure all 4 tyres were the same size??

Looking forward to some input, if I've done it correct there should be an image of the Alloy attached....

You can fit tyres of different width as long as they are on the same axle, although personally I would prefer them to be the same size.

There's no reason to have two different widths if the profile is the same. Someone either made a mistake or fitted whatever tyre was cheapest.

What size does the handbook say?

Could it possibly be that the 235's go on the rear and the 225's on the front as they will be on the steering axle??
They guy I bought them off said he took them off a 2010 plate Astra H (not sure if that makes a difference coming off an Astra??)

Do you reckon it would be safe to have them all fitted with the 235's as I personally don't like the way the 225's don't protect the alloy rims as much....

Hi
When it comes to 19" wheels, my Vectra Owner's Manual (the book that sits in glovebox) only lists one size and that is 235/35/R19 but no mention of the Speed Rating (although even though the current fitted tyres have different widths, they all have letter W..)

On the astra the 225's may have been on the front to stop rubbing on the inner wheel arch as the 235's may have been too wide and were rubbing

Vectra 19's were factory-shod with 235/35/19 tyres, speed rating 'Y' (186mph max), and Extra Load 'XL'. Load rating on hatchbacks was '95'.

As already been said......
225/35 on the Astra help with clearance when really low.
235/35 is the correct size and
245/35 fit the Vectra/Signum and give a bit more comfort and rim protection. Also makes the speedo pretty much spot on to GPS speed.

You say the 19's should be speed rating 'Y' - All the tyres that came with these alloys are rated 'W'.
I was planning of using the tyres already fitted considering the amount of tread left or would that now be a bad idea and get them all replaced before putting them on the car??

Thanks
