Just thought I'd post an update to let you know that this hasn't gone away.
It was originally raised in this thread: http://bb.bc4x4.com/showthread.php?113558-Final-Approved-Legislation-for-Lifted-Vehicles
I posted this on another message board but I've been busy so I forgot to post it here.
What brought this to my attention was proposed regulation in Saskatchewan that while generally reasonable, specifically set an arbitrary tire size of 35". Tires larger than that faced restrictions on GVW and highway speed, regardless of what the vehicle in question was. The proposed Saskatchewan regulation was shelved in November last year. According to SGI (Saskatchewan Government Insurance?? ), which functions much the same as ICBC, the regulation was shelved in order to bring it into line with the findings of the Working Group on Excessively Raised Vehicles. I believe however, that it was also set aside, at lest partially, because of a grass roots letter writing campaign that sprang up last summer.
Secondly, it seems that the Working Group is trying to standardize regulation across Canada with the goal of standardizing lifted vehicle regulation across North America. Here is the draft regulation proposed by the American Association of Motor Vehicle Administrators (AAMVA). http://www.aamva.org/aamva/DocumentDisplay.aspx?id={80881E2C-DD7D-4908-ADAB-309BFF9B3406} On the face it looks very similar to the existing B.C. regulation but again, like Saskatchewan, there is an arbitrarily set tire size limit only this time it is 34".
Further, both the US and Canadian initiatives are directed at regulating only "excessively raised" vehicles without consideration of heights of excessively lowered vehicles. This and the portrayal of the issue in last summer's CCMTA newsletter presents as bias solely against lifted vehicles. http://www.ccmta.ca/english/pdf/ccmta_news_summer_2009.pdf
Here is an e-mail that I sent to the Chair of the committee.
The Canadian Council of Motor Transport Administrators (CCMTA) is meeting May 16-20, 2010 in Fredericton and that date is is coming up fast.http://www.ccmta.ca/english/pdf/dv_agd_tentative_may_2010.pdf I think we as a group need to get need to get motivated and make our voices heard! I encourage each and every one of you to write a letter. I think what we need are individual letters as well as club/group affiliated letters. The only thing we need to be sure of is that our letters are articulate and respectful otherwise they will be disregarded by these bureaucrats.
Here is the letter that I sent to SGI last July if anyone wants to use it as an example. I discourage you from copying it directly as form letters do not carry any weight but feel free to add to or expand on any of the points that I made. Unfortunately the SGi draft copy has been taken down off their website so the quotes withing my letter are all that I have.
If anyone else has any other information or links please post it here.
Thanks,
Paul

Subject: Working Group on Excessively Raised Vehicles
Hello Daniel,
I was reading that you are the Chair of the Working Group on Excessively
Raised Vehicles for the CCMTA. As a concerned stakeholder I am wondering
if there is any avenue for public input on the issue and if there was a
way to see the minutes of these meetings.
Thank you,

Dear Mr. Gagnon:
A technical working group has been assembled by the Canadian Council of
Motor Transport Administrators ("the CCMTA working group") to examine
the safety issues associated with excessively raised vehicles. It is
anticipated that the scope of the work will involve preparing a best
practice document before the CCMTA Annual Meeting in May 2010. The CCMTA
working group intends to make arrangements to obtain feedback from
stakeholders should a draft version of the document be prepared by March
2010. In the interim, the CCMTA working group welcomes input from all
stakeholders with an interest in highway safety. As such I would
encourage you to provide a written summary of concerns that you as a
vehicle owner and/or member affiliated with a 4x4 club may have which
could be considered by the CCMTA working group in developing a best
practice document.
Thank you for taking an interest in the CCMTA working group.
Daniel Filiatrault, Chair
Excessively Raised Vehicle Technical Working Group
Canadian Council of Motor Transport Administrators
The Canadian Council of Motor Transport Administrators (CCMTA) is meeting May 16-20, 2010 in Fredericton and that date is is coming up fast.http://www.ccmta.ca/english/pdf/dv_agd_tentative_may_2010.pdf I think we as a group need to get need to get motivated and make our voices heard! I encourage each and every one of you to write a letter. I think what we need are individual letters as well as club/group affiliated letters. The only thing we need to be sure of is that our letters are articulate and respectful otherwise they will be disregarded by these bureaucrats.
Here is the letter that I sent to SGI last July if anyone wants to use it as an example. I discourage you from copying it directly as form letters do not carry any weight but feel free to add to or expand on any of the points that I made. Unfortunately the SGi draft copy has been taken down off their website so the quotes withing my letter are all that I have.
I am writing in regard to your proposed after market raised vehicle legislation. For the most part your proposed regulations seem to be reasonable but the tire size restriction appears to be completely arbitrary. I have added the tire size restrictions as a quotation and will outline my concerns about this below.

The proposed regulation states that installation of larger tires necessitates an increase in the height of the vehicle. This assumption ignores the fact that many new pickup trucks currently available on the market allow fitment of tires with a diameter of 35 inches without any modification to suspension or bodywork. This assumption also ignores the fact that current trends in four wheel drive truck/SUV modifications tend toward keeping the overall vehicle height as low as possible while increasing the ground clearance as much as possible. In this effort 4x4 enthusiasts are increasingly undertaking the widening of wheel well openings to fit their larger tires rather than increasing vehicle height.
The regulation also makes assumptions about the braking ability with larger tires while at the same time ignoring the fact that most often the installation of larger tires is accompanied by upgrades to the axles. The heavier duty axles most often have larger brakes which negates any supposed lost braking power caused by the larger tire diameter. It is in fact quite common for a vehicle to have better braking with larger tires specifically because of the upgraded axles and brakes. Further, most modern 4wd vehicles have much improved factory braking systems (such as four wheel disc brakes) over their earlier counterparts. As such it is not unheard of for a new 4x4 with larger tires to stop faster and safer than it's equivalent model from just a few years ago, that is equipped with factory tires.
The final assumption that the regulation makes is that the vehicle would be a hazard while towing at normal highway speeds. Quite frankly, restricting the speed to 20 km/h below that of the rest of the traffic on the highway is more dangerous than any imagined danger from the larger tires.
In addition the proposed regulation does not specify how the tire size will be determined. It is a well known fact that true tire diameters are often different than manufacturers labeling. How will this regulation be enforced? Will each police officer be equipped with a caliper or will the tire's diameter be determined from the manufacturers (often ambiguous) sidewall markings?
Overall the proposed legislation seems well balanced and thoroughly researched with the exception of the tire size restriction. If a vehicle meets the frame height, bumper height, suspension and steering criteria what need is there to restrict the tire size? Indeed, it could be said that larger tires afford increased stability as they are more often than not wider than their factory installed counterparts. I for one would be much more concerned about a vehicle that is at the maximum allowable frame height with relatively small tires installed than I would about a vehicle that is below the maximum frame height with larger tires installed.
I urge you to reconsider this part of the proposed legislation as it is unreasonable and superficial. It appears that the tire diameter restriction was included without much forethought as to the actual impact that tires larger than 35 inches diameter pose and without consideration of how it will actually be enforced.
Thank you for your time,
Paul Gagnon
