Looking at some B'stone D693's
265/75R16 $215
275/70R16 $225
265/70R16 $259!

any trouble in fitting any of these to the Jack.
It doesn't sag at all and is not raised. Normal!
245/70R16 are the norm.

75% Bit 15-20% sand 5-10% gravel

Hi Wolf, Why 265 instead of 245? The extra width doesn't do a thing for the Jacko. The slightly larger diameter, 75R16 instead of 70R16 is good, gives that transfer box guard a little extra clearance and no ill effect on acceleration that I can detect.
I have just worn out a set of Hankook 245-75R16 Dynamic Radials at 55,000 km., about 75% off bitumen in gravel, rocks, sand etc with no problems and no punctures(touch wood)! Have replaced them a week ago at $180 each fitted and balanced.The larger diameter makes the speedo and odo about 5% fast which must be taken into account when using for navigating long distances. Keep that Jackaroo rolling!

Jackaroo hi,

Which model Hankooks did you get?
I had the Z36 a while back on the old Jack.
I contemplated getting another set for the '94
but have heard too many hmmm's and mmm's
when I mentioned the brand.
I know the mine sites use them and have done so for
many years now.
Sizes...well, wider by 20mm is not that much and I figure
for the beach It would be better, a slightly larger footprint.
the 265/75 is taller by ~6mm than the 275/70 (if my calc are right)
and the 275/70 is now starting to get a bit wide.

Cost is a factor for me. I don't want to spend much over $200 per tyre.

That $200 saving will get me a spare which I need to match the new size.

cheers
wolf

Hi Dogart legally for a jack you can only increase it buy 15 mm wide.
I run 245 on sand and tow a trailer no problems.

G'day Wolf
Dad has a T/diesel Jack slightly raised and couldn't fit a 265 tyre at all due to rubbing.

Rads,

I know a fellow with 265/70 and has no problem on his jack. 265/75 apparently rub a bit as do 275/70's.

G'day Wolf...

265/75 and 275/70 are likely to rub. I know one guy with BFG a/t 265/70 without problem.

I agree with Jackaroo. 245/75 will give you the same lift as a 265/70 and should cost less. Probably less than the 245/70 too!

When Bruce Garland and the Holden Rally Team were racing their Jacks around the desert, they used 7.50R16 in a competition tyre (Bridgestone Dueler R/T - about $800 ea). No mods to the guards and no rubbing.

Just to clarify ... I'm not suggesting you go for the $800 Dueler R/T's.

I'm just suggesting you look at the 7.50R16 size.

Hi Savvas,
750R16 are tube type only, and a little too skinny for the Jack's 7 inch rims.

thanks all,

I was originally looking at 245/75R16 in the
BFG long trails.
This was back in nov last year.
Put it off, but now we are going up to kalbarri in
a coupla weeks and I'm risking the trip on the old
goodyears with 3 mm left!! No Way!

I was asking about these sizes as these were thrown at me by the
tyre shop cause they are on special.

the D693's don't come in 245/75

I shall ring around for more $ for the 245/75

your replies have swayed my choice back to "not pushing the boundries"
safer me thinks

cheers all again

Hi Wolf, Hankooks I am using are Dynamic AT RF03. One theory for sand driving is that a narrow tyre with a larger diameter will work better as it does not create such a bow wave in front of each tyre, works for me. Will watch out for you in Kalbarri, 99 white ITD, Cheers, Jackaroo.

Hi wolf, Local, will do, weather's always great up here. Check with Ambrose at Kalbarri Tyre Service on the Hankooks, I seem to recall he said the Rf03 was running out, don't know what its replacement is. Catch some big ones! Cheers Jackaroo.

Dogart,

You seem keen on Bridgestone - nothing wrong with that but there are plenty of good brands around. I thought the 693's were being replaced by the 694's. Also some 693's were of a weaker construction - Bridgestone Australia modified the construction of the locally made tyres.

245/75 are LT construction and many of them will have a load index of 120. The 265/70 are the same diameter, passenger (P) construction with a lower load index of 112. The extra 20mm width counts for nothing offroad. Might get a few extra k's out of the 265's.

So the 245/75 are actually the stronger tyres and more suited to the vehicle. They'd be my choice for that vehicle. The 265/75 may rub, unless you plan on a lift.

Cheers
Phil

Phil hi,

been looking at all brands
originally the BFG long trail in the 245/75
only got onto the bridgestone because a mate who's
a 4wd driving inst. suggested the 693's and plus when I rang
up B/stone they offered me a size for $215.
Cost is an issue for me.
$200 a tyre is about all I would really like to pay.
And I know that the extra $40 to get a BFG or Cooper and
even the 693's. is prob money well spent.
But I need a spare too!

Will prob spend the extra, be in pain for mmm coupla hours
then relise that I've done the right thing!

Will ring around and see who is willing to give me the best deal.

Dogart,

I usually buy 4 tyres at a time - you could get them to throw one used casing in for your spare. Most dealers will do this to clinch a deal. Might widen your choice of rubber. I think I'd be going for the 245/75 661's before the 245/75 693's.

Get a price on Kelly Safari AWR - I have a set that cost $217 each for the 265/75, and they have been a good tyre so far. My other set are MTRs.

Decided to go with Bridgestone D694's 265/70R16
@ $228 each inc fit & bal
the guy is swapping an old Olympic that's never been used
for a 265/70R16 with 80% tread.
Then getting the alignment done at suspension shop plus
tweak the torsion bars for $50.

I'm sure I wont know myself with any new rubber,
but the reports that are coming in for the new 694's
are very promising.

plus a review...

"The Chevy Blazers were outfitted with Bridgestone’s new Dueler A/T REVO. This is a light truck and SUV tire with Uni-T AQII. The tire uses a dual-layer tread compound for improved grip and traction, and superior braking power even when worn. Both the Bridgestone and competitive tires used in this test were purposely shaved down to 50 % tread depth and then "aged" or heat treated in ovens for several weeks to simulate substantial use and tread wear. This process is called "heat cycling" and it duplicates the process of vulcanizing - which hardens -the rubber compound that happens with daily driving of all tires.

The road test was designed to demonstrate the improved wet traction and gripping action of the dual layer tread compound used in the Bridgestone Uni-T AQII tires versus a major competitive product after substantial use and tread wear. What happens is a novel idea - as the tire wears, it exposes a softer compound of rubber, which offers the improved grip over the life of the tire.

Although none of the test drivers wanted to push these SUV’s to the limit as we did in the BMW’s, we did all drove them aggressively and pushed them through the turns and slaloms. The SUV’s outfitted with the Dueler A/T REVO provided superior performance over the competitive brand.

I noticed a better sense of control in the road handling and the ride was noticeably quieter, but the real difference was in the steering response. When I turned the steering wheel, the Blazer immediately responded in proportion to the turn. In comparison, the competitive tire offered slower steering response, which translated into less confidence in the tire.

After testing all tires on both vehicles as both driver and passenger, we evaluated the tires collectively. The results were consistently in favor of the Potenza RE750 and the Bridgestone Dueler A/T REVO - billed as the "Civilized Premium All-terrain Tire."

At the end of the day however, none of us needed the results of the questionnaire to prove that point. If standing cones can tell a tale, there were definitely more cones knocked down with the competitive tires -- and a few more fishtails and spins as well.

After returning home from the test, I got my penny out to test the treads of my tires. It’s an exercise - along with checking tire pressure - which I advise every driver to perform with regularity.

An afternoon of racing vehicles on wet pavement, I really wanted to be certain that I was prepared for the rainy storm that was to keep our streets wet for the next week or so. Altogether, I was impressed with the wet and dry performance of the Bridgestone tires."

will give a report when we get back from Kalbarri.
WOOOHOOO!
