This guideline is published to hopefully describe the BSR operate flat procedure equipped to the Toyota Rav4 T180 and SR180
Several owners have acquired their automobiles without the need of information of this BSR procedure so here I will attempt to describe what it is and the options for replacing it..

What is the BSR technique?

It truly is a Operate flat system that is various from other sorts where the sidewall of the tyres utilised is intensely reinforced so if a puncture or deflation takes place the auto effectively rides on the sidewall

BSR (Bridgestone Protection Ring) is a technique that employs a ring that is fitted inside of the tyre around the rim. This is what the auto rides on in the party of a deflation. The tyres are properly a usual tyre. This is a improvement of a WW2 military services vehicle.

There is also a lubricant inside the tyre that lubes the tyre and the BSR ring in the event of a deflation. With no this the friction created would demolish equally elements.

Technique is backed up by a TPMS (Tyre Strain Monitoring Method) that illuminates a warning gentle on the dash if a deflation will take position…

The pluses to this method..

It implies that no spare wheel requirements to be carried.. And… Err very well that’s about it really..

The minuses..

The tyres have to be eradicated by a unique and pretty high-priced equipment that only Toyota Sellers and a couple of independent Tyre Dealers have.

Only 1 kind of Bridgestone tyre can be made use of with the BSR program. No other make or model of tyre can be utilized.
This tends to make for costly replacements come time for new tyres and can demonstrate quite inconvenient in the event of a puncture.

Entrepreneurs report extremely pricey prices for alternative or maintenance!

The selections…

Very well House owners can merely dwell with what they have and set up with the what is considered large fees of replacement or maintenance.


Take away the existing tyres and the BSR technique absolutely. You can have the tyres eradicated by an Equipped Vendor as described previously mentioned. Expense all around £45 per wheel OR simply just lower the tyres of and take out the basic safety inner rings with the help of an angle grinder.

The TPMS procedure can be retained or eradicated and switched to protect against the light-weight flashing on the sprint..

At the time tyres and rings have been taken out standard tyres can be equipped on a normal tyre machine by any Tyre Dealer and any model can be used.

Coverage implications…

You ought to notify your coverage corporation if you get rid of the BSR procedure and match normal tyres.

No excess quality is likely as the motor vehicle will be as the most up-to-date specification SR Rav4. IE no BSR method and a tyre restore package in the boot.

It is feasible to have the tyres and the BSR ring removed then refits the tyres but this will invalidate your insurance policies for the reason that the tyres have a symbol on the tyre wall which designates them as Operate flats. Which of study course devoid of the BSR rings within they are not! This could imply that a Driver who does not realise this could operate into issues if a deflation takes place and he or she carries on driving…

Trip Quality

The wheels with the further body weight of the BSR process and lubricating gel is substantial in comparison to a wheel equipped with a regular tyre.

The suspension has two components to contend with:

The sprung bodyweight. This is the weight of the Car, Its occupants, Cargo and so forth.
The unsprung pounds. This is the pounds of the Wheels, Tyres, Brakes etc.

Relieving the suspension of the unsprung bodyweight enables it to get on with the occupation of managing the sprung weight. This provides up to a considerably significantly smoother trip with out the crashing and thumping that the amplified pounds of the BSR equipped wheels give. Try to remember the tyre partitions are Not bolstered..
The ride excellent is MASSIVELY Improved when the BSR is removed!!!

A thing to consider…

If buying and selling in a BSR outfitted RAV to a Toyota Supplier a person of the 1st questions questioned will be does it however have the operate flats?? Because if it does not the vehicle has in their eyes been radically altered and can not be marketed below the Toyota authorized motor vehicle scheme.

Other dealers may perhaps or might not question based if they know about the existence of the method in the to start with spot…

Hope this can help
