This information is written to hopefully clarify the BSR run flat system fitted to the Toyota Rav4 T180 and SR180
Many house owners have purchased their automobiles with out information of this BSR system so right here I’ll attempt to clarify what it’s and the choices for changing it..
What’s the BSR system?
It is a Run flat system that’s completely different from different sorts the place the sidewall of the tyres used is closely strengthened so if a puncture or deflation happens the automobile successfully rides on the sidewall
BSR (Bridgestone Security Ring) is a system that employs a hoop that’s fitted contained in the tyre across the rim. That is what the automobile rides on within the occasion of a deflation. The tyres are successfully a standard tyre. It is a improvement of a WW2 navy car.
There may be additionally a lubricant contained in the tyre that lubes the tyre and the BSR ring within the occasion of a deflation. With out this the friction generated would destroy each parts.
System is backed up by a TPMS (Tyre Stress Monitoring System) that illuminates a warning light on the sprint if a deflation takes place…
The pluses to this method..
It implies that no spare wheel must be carried.. And… Err properly that is about it actually..
The minuses..
The tyres must be eliminated by a particular and really costly machine that solely Toyota Sellers and some unbiased Tyre Sellers have.
Just one kind of Bridgestone tyre can be utilized with the BSR system. No different make or mannequin of tyre can be utilized.
This makes for costly replacements come time for brand spanking new tyres and may show very inconvenient within the occasion of a puncture.
House owners report very costly prices for alternative or restore!
The choices…
Properly House owners can merely dwell with what they’ve and put up with the what is taken into account enormous prices of alternative or restore.
Or
Take away the prevailing tyres and the BSR system fully. You may have the tyres eliminated by an Geared up Seller as described above. Price round £45 per wheel OR merely minimize the tyres of and take away the security interior rings with the help of an angle grinder.
The TPMS system could be retained or eliminated and switched to forestall the light flashing on the sprint..
As soon as tyres and rings have been eliminated regular tyres could be fitted on a standard tyre machine by any Tyre Seller and any model can be utilized.
Insurance coverage implications…
You need to notify your insurance coverage firm in the event you take away the BSR system and match regular tyres.
No further premium is probably going because the automobile shall be as the most recent specification SR Rav4. IE no BSR system and a tyre restore equipment within the boot.
It’s doable to have the tyres and the BSR ring eliminated then refits the tyres however it will invalidate your insurance coverage as a result of the tyres have a logo on the tyre wall which designates them as Run flats. Which in fact with out the BSR rings inside they aren’t! This might imply {that a} Driver who doesn’t realise this might run into issues if a deflation happens and she or he carries on driving…
Experience High quality
The wheels with the additional weight of the BSR system and lubricating gel is big compared to a wheel fitted with a standard tyre.
The suspension has two parts to deal with:
The sprung weight. That is the load of the Automobile, Its occupants, Cargo and many others.
The unsprung weight. That is the load of the Wheels, Tyres, Brakes and many others.
Relieving the suspension of the unsprung weight permits it to get on with the job of controlling the sprung weight. This provides as much as a far far smoother journey with out the crashing and thumping that the elevated weight of the BSR geared up wheels give. Bear in mind the tyre partitions are Not strengthened..
The journey high quality is MASSIVELY IMPROVED when the BSR is eliminated!!!
A consideration…
If buying and selling in a BSR geared up RAV to a Toyota Seller one of many first questions requested shall be does it nonetheless have the run flats?? As a result of if it doesn’t the automobile has of their eyes been radically altered and can’t be offered underneath the Toyota accepted automobile scheme.
Different sellers could or could not ask relying in the event that they know in regards to the existence of the system within the first place…
Hope this helps
