Hi all,

Im upgradeing from my 31x15 size tyre to either a 33 or 35 but am not sure what the difference between them is? ie. stability, tyre wear, traction. so could some one please help me out here?

Also for this upgrade im tossing up between cooper st and the BFG muddies, iv herd the BFG's wear uneven and are a pig to drive with on the road is this true? Also iv heard the cooper has a bad reputation is this true?
maby some adv/disadv of both would realy be apprieciated.

Thanks guys i hope you will be able to help me out, Tom

New BFG wear out fast.
STT's wear out faster

both are average on the road.

33/35 need engineers certificate to be legal, if your in QLD forget it. Your insurance will also have to be told.

Go with MTR's Ive had BFG and MTR' MTR eats and spits out the BFG's. Drives good on road, but none are as good as AT's on road.

Tom,
Going to a bigger tyre is always a compromise.
Issues to think about are:
1) changes to gearing. You haven't said what you're driving, but whatever it is, you'll notice it'll be a lot slower off the mark and you'll have to paddle it up hills with the gear lever if it's a manual. Of course, if you change your diff ratios, that'll solve that problem
2) downhill engine braking will be affected as per above and same cure (change gearing).
3) Speedo will be out a fair bit (could be up to 10% or more with the 35" jobbies)
4) Legally I think you're only allowed to go up one size in most states. So you could have the boys in blue after you and as for the insurance companies....they'll wipe like a dirty bum!!
5) I've had BFG muddies (265/75R16) and did about 45,000klm and they were about 2/3rds down and started to make road noise and became skittish on wet roads. I've now put them on camper trailer/spare and bought same size Cooper S/Ts. Only done about 5000klm so far. They are going good and are quieter. They seem to be more aggressive tread pattern than the BFG A/T, but not as luggy as the M/Ts.
There are probably other issues I haven't thought to mention. I was considering going up to 285s when I bought this set of tyres, but as I use 9 tyres in a set (4+2 on truck and 2+1 on camper) it would have cost me 2 of my kids to change 'em all over at once.
Cheers,

Roachie,

I have just figured out why you are at the bank! It must be the only way to be able to buy 9 decent tyres in one go!!!!! What was the saying - one cent each day from every account.....

Steven,
Yeh, I wish!!!!!
The only time I've ever bought nine new tyres at the same time was when I bought the Patrol new.
As I said before, I'd have to sell-off 2 of my kids to be able to afford to do THAT again!!! LOLOL
BTW; good to hear you had a great maiden country trip on the weekend and called on Willem and Pesty. If you're up here on the YP anytime, you'd better drop by....just make sure you park in front of the neighbours place though, won't you. I wouldn't want any passers-by to get the wrong idea, like I'd gone all soft and bought a Playdoe!! LOL
I'll bet Pesty let you park in HIS driveway, eh??? LOL
Cheers mate

And just WHAT is wrong with the Playdoe may I ask! (apart from the Toyota badge on the front according to YOU!).

I parked in Pesty's driveway head to head with his 'cruiser. I am sure I saw the cross bars on the roof rack rise up like the hairs on a cat's spine! Willem seemed quite OK with the Prado out front of his place, mainly because Rosie was hiding out the back!

Mind you if I park near your Nissan I will need to watch out for lightning bolts with the amount of electrical accessories that you have bolted in/on!!!

Keep the coffee hot!

Sorry mate. I think you are confusing it with the KLUGER!

No complaints on the Prado's off-road ability so far. I see the GQ needs a LIFT in order to go off the bitumen!

I thought looking "Horn" was for posers. I wouldn't class the GQ as a poser's ride!

Just seeing if the red rag still works... lol

I went from standard tyres to 33 x 12.5 x 15 BFG All terrains on my old troopy. The ride was surprisingly quiet and stable.The gearing obviously changed slightly however I have never had a problem holding fifth and dont notice any difference off road. Low range work has never suffered either.

I am just about to buy 6 new tyres for a troopy I am waiting on and was informed by one of the tyre retailers that both BFG and Coopers have recently changed their rubber to a softer compound. I am not sure which way to go now as I was extremely happy with the wear and ride of the old BFGs. One horror story from the retailer who sells both was 100 series toyota with BFGs had one trip down the birdsville track and nearly destroyed all 4 tyres. The same retailer stated that the WA rep for Coopers told him he would be waisting his money on the new Coopers. Sounds a little extreme to me?
I am now looking into other options.

Regards

Bart

Tom,
I've always had a good run from Yokohama Super Digger V's on road and rock & they aren't expensive.
