Cooper ST v BFGoodrich MT

Hi
The Cooper ST and BFG MT's are very different types of tyre. The ST is a road oriented A/T tyre while the BFG's MTs are a much more offroad orientated tyre.
Hence you will find the ST will be a quieter longer lasting better road handling tyre than the BFG MT. On the other hand the MT will be much better off road, especially in mud where its open designs clean better.
The BFG A/T would be a tyre similar to the Cooper S/T.

In the key 5 factors the only real difference is that there is no significant difference.

There are secondary differences and off course the visual difference of a different tread pattern to assist with image of a new product.

if you go to BFG site as below and use the search box you will see those 2 are rated the same (6,4,10,7,5) total of 32
If you call up the BFGAT instead you will see it is rated 9,6,9,8,6 for a total of 34 points.

Straight away you can see the BFG AT has significantly better fuel consumption and dervied from this less noise etc.

You have not said car type- Petrol, or less powerful diesel , 285 muddies overly
affect 3lt diesel driving performance IMHO

I wouldn't use muddies for everday use either, espically that size if a diesel as its braking performance is a bit weak to start with.

I have a set of Cooper ST for my 4800 GU, but only because they make my preferred off road size of 255/85/16 and no one else does a non-muddy.
I could not reccomend them otherwise.

Hi

The problem your going to have is overall tyre height

275/65R17 = 77.63cm
285/70R17 = 83.08cm

This is a difference of 5.45cm. Most states only allow 1.5cm difference.
It's going to affect the roadworthiness of the vehicle and it will dramatically affect you speedo reading, plus most insurance mobs don't like it either.

Hope this helps
Cheers

I had Cooper ST's & since I have had both the BFG MT's & MT2's...

The ST's chipped badly in the high country whereas the BFG's have shown a lot less.

When I got the car @ 35,000km it alread had the ST's on. They lasted till 95,000km.

The BFG MT's lasted 95,000km & we drive the car virtually 95% road to & from town & only 5% dirt, of which perhaps 2% is 4WD - High country, Fraser etc.

The ST's had also badly scolloped, The BFG's didn't show this when replaced.

The BFG is a stiffer tyre also in the side walls, makes the ride a little harder for the same pressures & you need to take more air out to get flotation.

The BFG's however tend to default to a longer footprint rather than a wider one - handy for sand. I just spent a week at Fraser in which we only used low range as a precaution for some of the steeper bypasses. All other times it was all high range even on the very soft sand above the high tide mark.

For me BFG's win hands down over the ST's!

I had 285 Cooper ST's on a 200 cruiser and found then great. Did not find chipping etc.

Now I have 305 BFG Mud K2's and like them also. Do not find them any more noisey than Cooper ST's. My understand is that the K2's are much quieter than the previous type.

Something to look out for is the date of manufacture of the K2's. Some of mine were 4 years old already even though just being released in Australia.

A previous post said the Cooper ST and BFG Mud are not the same tyre. I think is is partly correct as Cooper STT are closer to BFG Mud. ST's are somewhere between BFG AT and BFG Mud.

Mostly I drive on sealed roads and find them great in wet and dry. They are great in the sand as well. So far not, funny enough been in mud.

I think you will like either.

main difference in my opinion is that coopers are high priced garbage and BF Goddrich are high price reasonable tyres.

I find this is a good starting point, site also has user ratings : http://www.tirerack.com/tires/types/maxtrac.jsp Useful guide (certainly not the 'bible'), and remember it is a USA site.

I have Cooper ST's on my Discovery, I thought they were good tyres for the first couple of years and had few issues. However as they are now 6-7 years old the rubber has gone hard and they are terrible in the wet, they also leak though hairline cracks in the casing. I know its not common to keep tyres this long but the original michelin spare has been on the back door exposed to the elements for 13 years and its still like new and rubber is soft. I'm going to give the BFG's a go this time even though I've heard they have had quality issues and balancing problems with the later tyres.

We get a pretty good run out of BFG all terrains on our vehicles. We have recently put mud terrains on the Cruiser as all terrains weren't available at the time. Now we just need the rain!

BFG's give better fuel economy and more accurate speed reading. This saves money as well as giving confidence in avoiding wildlife strikes. Not rubbing the blue off the letters when new makes the side walls last a lot longer as well.
