Thread: D3 18" off road tyres?

thanks BigMac. My current wranlgers are almost dead at 25k's, so 40k is great. User surveys on the AT2s look great (http://www.tirerack.com/tires/survey...'type=ORAT), so I think I'll put my order in for them. Thanks all for the help. Cheers Lance

I have been doing a fair bit of research on tyres for 18's lately.
I have come up with the following options;
1. Mickey Thompson ATZ's in 275 x 65 x 18 = 32"
2. BF Goodrich ATKO's in 265 X 65 x 18 = 31.5"
3. Goodyar Wrangler Silent Armour in 265 X 60 x 18 = 30.5"
4. General Grabber AT2 in 255 x 65 x 60 = 30.04"

All of the above tyres will fit however the Mickeys will rub ever so slightly.
comment received on the D2au site indicates the Mickey's to be the best tyre but boy are they expensive - I priced them for $430ea.
Others have also reccomended the Silent Armours & the Generals.

In addition Mickey Thompson are about to release a 4 rib more aggressive version of the ATZ in 275 x 70 x 18 = 33.15" these may not fit, however they are nearly as aggressive as a mud terrain.

If you have 19" rims you can get Goodyear Wrangler MTR's in 255 x 55 x 19 = 30".

To my knowledge there are no mud terrains in 18" that will fit landrover discoveries without huge lifts & body cutting.

hope this helps

Hi Stevo,

Just changing the subject a bit. I noticed in your photos you had a UHF radio. Can you tell me where you have the arial.

Regards

Hey mate, I just have a hand held for now for convoy trips that I go on with the club. However my rear bar has a spot to put an aerial once I get an incar UHF radio.

Steveo,
Are u running 18's as yours is an HSE, so originally u would of had 19"s.
You keep saying u are running 255/55's. (255/55/19-Originally)
Just want to double check as General make the tyres for both the Sport & D3 in 18".
Sport is 255/55/18
D3 is 255/60/18 which is slightly higher......i did say slightly..
If u are running 255/55's (18)then they are the wrong size! for the D3...

Yes, originallyhad 19 inch rims, then bought GMAx 18s. D3 is also 255/55/18 as well, so they are correct.

The good news is that finally tyres are coming out, it has been a wait since having mine from Dec 05 . WHen the Grabbers have seen there term I will be looking at either the BFG's or Mickey Thompsons, simply as they have a higher profile,

Regards

Stevo

Hey Chuck, can you elaborate on that...ie how/when do they rub, thanks,

regards

Actually Stevo, don't mean to rain on your parade (or highway in case the traffic stops), but...

In some states (such as here in WA) the 255/55/18 is illegal for two reasons:
1. the overall diameter is 25mm less than standard and the law allows for only a 15mm difference; and
2. The load index is only 109 and the D3 requires a 110 or above.

The 255/60/18 Grabber is Ok I believe.

Ooookkkaaayyyy, I may stand corrected, they advertised the 255/55/18's for D3's and took at face value. It doesnt have 255/55/18 on the tyre placard, but also doesnt have other sizes that will suit either. How do you work out the "mm" in respect to the sizing?

Stevo

to you too Jamo

The 255 is the width in mm.
The 55 is the percentage of the width that the sidewall height is.

ie 55% of 255 is 140.25mm for each sidewall = 280.5mm total
18" rim at 25.4mm per inch = 457.2mm
thus the total diameter is 738mm.

Of course this will vary with tyre pressure and tread wear etc.

The nominal diameter for the 255/60R18 is 763mm.

I doubt having the 255/55's is going to cause any real trouble though. I've never had either the police or an insurance company check anything other than tread depth.

I don't doubt that they advertised the tyres a suitable. I still get salespeople trying to tell me anything that fit's a D2 will fit a D3.

I have a $420 question. I've decided on buying 4 of the Goodyear Wrangler Silent Armours (265 X 60 x 18 - best quote I have is around $420 each), and have been told by two tyre places that I dont need to change my spare (factory goodyear 255/60/18) as its within the 15mm tolerance (so long as I dont keep it on for more than a few months), BUT 2 other tyre places have said my disco will fall apart immediately if I use the spare with the 255 on. If I do get a flat I would obviously change ASAP (granted that it may be a few hundred k's), but what do you think - is there a risk or are these tyre places really full of crap?
