Difference between Tyre brands / on the road.

[~Rich~]

Hi all,
I regularly swap between my two sets of tyres, General Grabbers AT 255/55 R19 and Cooper LTZ Zeon 285/60 R18's

I've got to say the difference is enormous.
The Coopers are by far so much more confident in feel and handling in all weather conditions on the blacktop.

With the Grabbers they feel a bit sqirmish cornering and do not give the driver much confidence in the feedback.
They feel like the D3 has more body roll as well.
I'm running the same pressure in both sets 38 front & 40 rear so this cannot be the factor.

Anyone else felt this with the General Grabbers?

G'day Rich,
I noticed the body roll was significantly more with the GG's than with the OEM Wranglers which gave more of a carlike feel, however as I only have one set running and love to take mine out I just have to suck it up, it would be interesting to hear other people's comments who run different tyres particularly AT's

Cheers
Julian

I swapped to GG's before delivery so haven't experienced without, but have always loved how the D3 handles.

With you on the Cooper LTZ's Rich.
Most confident on road tyre I have had, and awesome off road.

Cheers, Craig

Big difference in tyre sizes there. 285-255, wonder if the sizes are more of a factor than the brands.

I haven't used either so cant comment,

Interested to hear what others say.

Cheers Ean

I forgot to say both sets are 2012 purchases so wear is also not a factor.
Wheel alignment was done with the GG's on recently.

In theory, shouldn't the tyre with a smaller sidewall...as in the 19", have less flex (roll)?

So if that's correct and the 18"s are better, the 19" must have soft sidewalls or something.

I changed from the puncture prone Wranglers to Scorpion ATRs (both 19"). Probably as good on the road, grip wise, as the Wrangler but much less flex, so a more direct feel. I operated both at placard pressures 33 & 36psi.

Much better offroad too. Sand, grass and rocks have been fine. Like all non mud tyres, they're not so great in lots of mud.

They also wear so much better too. I've done over 30K on them and they still look near new. The Wranglers were under half tread by that stage.

Cheers,

Kev.

I have to say that the 19" GG's are very ordinary on the sand when compared to the 30mm wider LTZ Coopers.
This of course is very understandable considering the sidewall height difference.
On the road I too would think the lower sidewall would improve handling with the GG's.

Hi Rich

I run G.G. in 255-60-r18 AT2 and Micky T mud in 265/70/r17

I really feel the body roll on the Mud tires but expect that.

I had some secondhand Mick T ATZ in 17 inch 245/70/R17 and really did not note much change if any between them and the GG AT2.

I wonder if there is much diferance with the GG AT and GGAT2 and also if the wide size of your Cooper LTZ Zeon 285/60 R18's compared to the width of 255 explains the very soild footing. How is the price?

There is also a school of thought that the road based tread patterns are better on sand as they tend to "float" on top, as opposed to ATs and MTs which tend to dig in. Not sure if there is any actual science in this but many swear by it.

[~Rich~]

This is not alway the case, the BFG Mud Terrain is better in the sand than the BFG All Terrain. The reason is the square edges of the All Terrain dig in easily especially when doing turns on the sand.

I'm starting to think it's the angled curved grooves on the GG that result in the less than confident handling on the road.
