2008 MRF TYRE REPORT

 

 Another five trips were undertaken during the winter of 2008. The results from the tyres were pretty much as expected. MRF tyres worked without issue in every terrain we came across. Have a good look at the third trip! In most cases we seem to be on top of the issues that cause us trouble. One problem remains with thinning tubes causing a few slow leaks for us as the season progressed. I’ll have to wait until 2009 before I can try a solution.

 MRF tyres are listed in blue.

 Off-Track or difficult country is listed in red.

 

Trip #1

 Off-Road Tour of 2140 kms in 13 days

 2 flats – three vehicles

Tyre on each vehicle Flats Cause Fuel Consumption
BIAS - MRF Super Miler - Land Rover 130 1 Sidewall stake 13.04 Lts/100kms
BIAS - MRF Super Traction - 100 Series 1 Tread stake  - 
S.B.R. - 205R16 - Mazda Bravo 0  -   - 

 Well there you go, we’ve finally had a trip where the BIAS copped the stakes and the Radials got away scot-free. There simply is no justice at all.

 Both stakes repaired easily, bit surprised by the sidewall damage, but guess it can still happen. All tyres serviceable and returned home OK.

 

Trip #2

 Off-Road Tour of 2420 kms in 18 days

 4 flats – six vehicles

Tyre on each vehicle Flats Cause Fuel Consumption
BIAS - MRF Super Miler - Land Rover 130 0  -  12.37 Lts/100kms
S.B.R. - Cooper STT 285 - Toyota 100 Series 1 Sidewall stake  - 
S.B.R. - 205R16 - Mazda Bravo 0  -  11.48 Lts/100
BIAS - MRF Super Miler - Toyota 80 Series 0  -   - 
S.B.R. - 30/9.50R16 - Toyota Hilux 0  -   - 
S.B.R. - 225/75R16 - Toyota Hilux 3 Tube rubs 12.97 Lts/100kms

 A pretty simple trip and no great problems for tyres, the tube rubs were left over sand and grit from the trip last year in 2007. That bloke has now learnt it is a good idea to strip & clean split rims when you get home as well as apply a bit of silicone for the trip.

 The Cooper STT below was a bit unlucky, but that is how it goes, had to use a 142TL patch for that one and it came up well. I included an image of the stake as it was such a good one.

 

Trip #3

 Calvert Expedition route of 1896 - 2070 kms in 27 days

 25 flats – seven vehicles

Off-road distance = 1310 kms
Off-track distance = 760 kms (no road or track at all)
Sandhills crossed with no road or track = 498

Tyre on each vehicle Flats Cause Fuel Consumption
BIAS - MRF Super Miler - Land Rover 130 5 Tread stakes 20.91 Lts/100kms
BIAS - MRF M77 - Ford F-250 0  -   - 
A.S.R. - MRF Steel Muscle - Toyota 80 Series 0  -   - 
BIAS - MRF Super Miler - Toyota 80 Series 0  -   - 
A.S.R. - MRF Steel Muscle - Toyota 79 Ute 2 Sidewall stakes  - 
BIAS - MRF Super Miler - Land Rover 130 3 Tread stakes  - 
A.S.R. - Michelin 305/70R19.5 - OKA Camper 15 Sidewall stakes  - 

 The toughest trip we have done to date. All tyres were temporary or minor repaired according to Rema Tip-Top specifications. Everyone drove home on the tyres they started with, a good result.

 The 19.5" tyres belonged to an OKA. Track width was his problem but we had plenty of repair gear so we could keep him going. As usual with All Steel Radials no cut or stretched sidewall wires were found.

 

Trip #4

 Off-Road Tour of 4125 kms in 27 days

 10 flats - seven vehicles

Off-track & overgrown wheeltracks = 180 kms

Tyre on each vehicle Flats Cause Fuel Consumption
BIAS - MRF Super Miler - Land Rover 130 2 Thinning tubes 13.82 Lts/100kms
BIAS - MRF M77 - Ford F-250 1 Tube problem  - 
S.B.R. - 205R16 Mitsubishi Triton (petrol) 0  -  15.03 Lts/100
S.B.R. - 235/85R16 - Land Rover 130 0  -   - 
BIAS - MRF Super Miler - Land Rover 130 0  -   - 
S.B.R. - 205R16 - Mazda Bravo 2 Sidewall stakes 13.24 Lts/100
A.S.R. - MRF Steel Muscle - Land Rover 130 5 Tube rubs  - 

 Bulk of the problems here were tube related. The fellow with 5 flats had taken his Steel Muscles on split rims to his local tyre man for him to dismount clean tyres & rims and fit new tubes. Our customer picked them up the next day. While on the trip he had slow leaks and each one I repaired we found that the tyre had not been touched, full of sand and a patched old tube. Hard to get good help these days!

 Ours was a different problem; our tubes are thinning in the sidewall area I suppose due to the great amount of time we spend at low pressure. Friction of tube on tyre, heat would be the cause. Next year I’ll change a few little things and see if I can stop this happening. I’ll keep you posted.

 

Trip #5

 Off-Road Tour of 1550 kms in 10 days

 1 flat - seven vehicles

Tyre on each vehicle Flats Cause Fuel Consumption
BIAS - MRF Super Miler - Land Rover 130 0  -  12.04 Lts/100kms
S.B.R. - 285/70R16 - Toyota 100 Series 0  -   - 
S.B.R. - 285/75R16 - Toyota 100 Series 0  -   - 
S.B.R. - 245/70R16 - Hyundai Terracan 0  -   - 
S.B.R. - 7.50R16 - Toyota 100 Series 0  -   - 
S.B.R. - 265/70R16 - Toyota Prado 0  -   - 
S.B.R. - 265/75R16 - Toyota 80 Series (petrol) 1 Sidewall stake  - 

 A straight forward trip on maintained roads for the majority of the distance.


 

  So for Beadell Tours & MRF another very good year for tyres, driving off-track we copped a few tread stakes, normal, and while driving off road not much happened at all. Only need to solve this tube thinning issue and it will be back to luck as to how things go. As we have said before there seems to be no reason to use anything else but MRF for our work.
