190/50/17 on a 5.5 inch rim....Certain death??

Postby Rufus » Sat May 22, 2021 2:59 pm

The Pilot 4 on my 1100S is getting quite badly squared of now, its a 180/55
I've got 2 new 190/50 in the shed waiting to go on another bike.
A. Will i encounter clearance issues ?
B. Am i certain to die first time out ?
Your collective wisdom is gratefully recieved :D

Regardless of the wrong size rim / tyre , here in Spain its one of the things always checked by ITV and Guardia Traffico , tyre size !

What ever the correct tyre size was for the bike, when manufactured, is the tyre that must be on the bike .

I'd personally not use such a big tyre, the profile will be all wrong to start with, and your handling will be suspect at best .

Just my personal opinion, others may prove me wrong.

Unless you have the wider wheel that is fitted to the sport and Boxer cup models the rear tyre size is 170 60zr 17 & 180 55zr 17 for the wider wheel, as Gerry says a 190 profile will be all wrong especially if you have the std wheel fitted.

I popped down to the shed with my trusty tape measure.
The current Michelin Pilot 4 180/55/17 measures 226mm across the width and 53mm at the side wall.
The new Metzler Rennsport(still a current tyre in germany) 190/50/17 measures 231mm across the width and 51mm at the side wall.
A 180/60/17 Supercorsa on my Aprilia actually measures slightly larger than the Rennsport.

I ran a 180 on the 5" rim and the handling was a bit odd but could live with it. Went into Blue Bell at Crewe for a service and was told to change it before the mot as it would be a fail. Paid yer money already, but your choice. I would stick with a 180 on the wider rim if it were me, but then I'm fussy about proper handling and having the insurance pay out if I am in an accident.

The insurance thing is a concern......might have to go tyre shopping.

Insurance are not allowed to deny a 3rd party claim based on vehicle condition it's specified in the Road Traffic Act.

You won't tear a hole in time and space fitting a 190 to a 5.5" rim but you might not like the way it turns. Certainly if I was on a budget and I had one spare I'd be fitting it.

However - in respect of 3rd party claims: If you have been deemed to make the bike unroadworthy (Roadworthiness being a prerequisite of the policy) - then.....

a) Yes - they will pay out to valid 3rd party claims.
b) They can and will - pursue the policy-holder for their 'loss'.


They can take all your assets and effectively bankrupt you.

In respect of a claim by the policy-holder for (say) the value of the bike in event of an accident where there are no other claimants other than the policy-holder (eg - you run out of talent and bin the bike to the extent that they write it off) - then they may also deny the claim on the basis of that non-approved tyre-size.

It's really not worth it (to me, at least).

Regulations have tightened right up in recent years, and none in the insurer's favour. They would literally have to prove that a loss was a direct result of fitting the wrong size tyre to the bike to have any chance of recovery. How are they ever going to ascertain that?

BTW your example is not of a third party claim. Binning your own bike is a whole different matter, you're going to lose the value of that if you have breached the terms of your policy.

I certainly wouldn't want to be fighting the underwriters on that one. If they are able to prove that 'had we known about the fitment of this non-standard tyre- we would not have offered cover' - I think the policyholder is on very shaky ground.

The example of binning one's own bike was not intended to be illustrative of a 3rd party claim.

Here in Spain , that tyre would be classified as illegal, as it is not "As built".
