Thread: Tyres for Disco 5

I am thinking of going with 20" rims and 275/55R20 tyres as the possibilities in 255/55/20 are very limited. My driving, when being realistic, will be 70% to 80% dirt/sand/rocky and the rest bitumen around town and getting to the dirt/sand/rocky stuff. It will be a V6.

the 255/55R20 tyres are 31" - 787mm - and the 275/55R20 tyres are 2.9% bigger at 31.9" - 810mm.

In 255/55R20 all I could find was:

Grabber AT3 110H XL
Goodyear Wrangler Duratrac 110H XL

In 275/55R20 I found many more options:

BFG KO2 115/112S
Nitto Ridge Grappler LT 120Q
Pirelli Scorpion AT+ 113T
Nitto Terra Grappler 117T
Dick Cepek Trail Country 117T
Falken Wildpeak AT3W 117T
Goodyear Wrangler DuraTrac 113S
Cooper AT3LT 120S
Cooper Zeon XL 117S

The two Nittos and the Falken seem good options, and the Ridge Grappler has the bonus of being LT275/55R20 and 120Q. I can get the Ridge Grapplers and Wildpeaks for $375 a corner and the Terra Grapplers for $340.

Ahhhh.... Decisions! Any thoughts, anyone? Experience? I tow around 2 tonnes and would really like to avoid punctures, but my days of hero tracks are behind me...

I am looking to trade our current D4 in on a D5 and have been running General Grabbers on our 19's in the D4 with out any trouble. I would go with the 3 litre D5 and 20" and have been told the following options match the manufactures specs :-

1) Good Year DuraTrac 255/55 R20 - 110QXL
2) Coopers SRX 255/55R 20

Changing to a 275/55/20 falls outside of the manufacturer recommendations. I have seen cars where this tyre change over was done and it seems to be fine - other than it will have a small effect on the speedo...

Thanks to the forum users here being open and honest with their experiences - I am almost ready to commit to a new D5

Thanks Scott

Thanks, Scotto.

I am in Adelaide at the moment, helping out at the4WD show. I will have a good look at the Goodyear Duratracs while I am here ad try to talk to a few people. I am thinking Duratracs in 255/55 R20..

The quest continues!

I just bought a Disco 5 with the 19inch wheels. At the moment, I’m not sure if the car will come with 235 or 255 tyres. Has anyone managed to find decent AT tyres that will fit nicely on these wheels?

My understanding is that the 19" rims come with 255/60R19 tyres. I cannot find any AT tyres in that size. You have to go down to 255/55R19 and there are several options:

255/55R19
Maxxis 980 LT 115/112
Pirelli Scorpion ATR 111H XL
Grabber AT3 111H XL
Hankook Dynapro AT-m
Pirelli Scorpion AT+ 111H XL
Toyo Open Country AT Plus XL 111H XL
Goodyear Wrangler Duratrac XL 111Q

Thanks, Numb Thumbs.

Going through the thread, there’s a bit of discussion in terms of whether that size is road legal or not - has anybody gotten to the bottom of this?

The 255/55R19 tyres are 26 mm in diameter which is 3% smaller - 789mm versus 763 mm. This seems to be not recommended.

Legalities wise, people always seem to talk about going bigger, not smaller. I tried looking on the VICROADS website and gave up.

Yea, that’s what I thought.

I’ve asked Goodyear Australia if there’s a way to order in from the US, as they have an AT tyre in this size.

Convince Pirelli to make their AT+ in the size that they already make in Verde All Season with its LI 113 rating for LRs. They were intending to make them, having issued a product code for it.
