Thread: D4 Low Tyre Profiles

Where all the others in the group travelling to Maralinga were on 70km/h at one point (about 20 km in front of me) due to corrugations - I caught up to them cruising at a leisurely 120km/h and felt like riding a magic carpet...

In fact, I called Basil135 (there is 3G along the rail corridor) to stir him up...

Throw on some 18s and chuck on some D697s they are an incredibly strong carcass and more than up to the task on the tracks you refer to...

yeah thanks Tombie.....I've got 697's on the D2.....they throw stones though....

I think the other mistake people make with 19's is to use the same approach to tyre pressures as you would for a tyre with higher sidewall. End result is a damaged tyre.

I will not take my 19's below 30psi when doing any rough work. This helps the tyre maintain what little side wall it has which helps to protect the rims but that means that I'm not going to get the same molding around track irregularities or lengthening of the foot print of tyres that can be lowered much further - in short, harsher ride and less grip over the rough stuff.

Sean,
Is this 30psi cold or hot.

That's hot Richard.

Thanks Sean. I suppose I should have guessed that.

Mine has 19" wheels and I've been through 4 sets of tyres over the years ... only punctures have been on the road ... as has been said great care must be taken (speed down, careful lines, tyre awareness) and it is unwise to lower the pressure much (frankly I rarely lower mine at all). I'm not hardcore like some around these parts, but my Disco has been many places on many trails on many differing types of terrain on 19" road tyres ... with a minimum of fuss, no significant tyre damage and no getting stuck (touch wood!).

In an ideal world I'd have a set of 18" with D697 on them and a set of 19" with high performance road tyres ... may happen one day ;)

You are sure tempting fate of the tyre gods

When towing it sure is hard to comfortably drop the pressure

I think I should make some kind of offering to please the tyre gods after that post.. Perhaps if I burnt some Chinese made tyres whilst singing a tyre themed song ...
