16 modulars from Defender on Disco 4

Recommended Posts

A friend of mine has bought himself a D4 which he wants to use for shoots. He is worried about getting stuck in the mud on his road tyres supplied with the vehicle.

What issues are there with the idea of lending him some BFG Muds 235/85/r16 on 16 inch modulars:

  • Would they fit?
  • Are the stud patterns the same?
  • Will the brakes foul the modulars?
  • Anything else we should know?

Also as a second idea, AT;s same size on Boosts if it works our easier.

Cheers

I know that D2 had different stud PCD than that of D1's and Defenders. So I would imagine that the D4 will also be different. Other thing to consider is gearing if tyre's diameter are different

Apart from those little nuggets of information can't help you more... Can you not just try one on the front to see for any interference?

No proper wheels and tyres will fit. You will find Grabber AT2s to fit 18" rims (255/55R18 or 255/60R18 will fit) or Goodyear MTRs in the 255/55R19 size to fit 19s. Not aware of AT2s being available in 19 or 20in sizes though I understand they may be soon ;)

I am pretty certain you won't find anything smaller than 17in rims to fit a D3/D4. This is pretty much in keeping with their role as a roadgoing machine used by people who want others to think they go offroad and the 0.1% that actually do use them offroad (assuming they manage to get there without breaking down) don't make it a big enough market for a proper off road tyre - the only reason the Goodyear MTR exists is because it was developed specially for the G4 challenge vehicles.

OK, Thanks for your responses.

Scrub that idea then.

He has had the car for 6 months so it is on new tyres which he does not want to change and he does not want new wheels/tyres for a few time use a year (0.1% won't be far off!). Oh well he will just have to make sure that he has recovery points at each end or that it is not too slippery!

The smallest you can fit to a D3 is 17" due to the brake caliper. I'm sure on the D4 with the 3L engine the smallest is 18" but if you have a D4 with the 2.7L you can still fit a 17" rim.

In 19" flavour the MTR is the most aggressive you can get. Fitted to the G4 challenge veh so must be fairly competent.

In 18" AT2 gets a fair shot but the sidewall is almost floppy. There are a few offroad biased tyres. If you look at Disco3 forum or Disco3club forum and have a peek in the tyre section there are loads of blokes using all manner of tyres for playing in the dirt. Mainly the Euro members from the BENELUX countries

If you fit spacers to a D4 and run 16/17" wheels and you have a problem then A your warranty could be void. B Your insurance won't like you for fitting whels of a size never fitted to the veh.

But at the end of the day you pays your money and takes your chance

So a tyre specificaly chosen by LR for their G4 fleet is carp?? I'm sure that LR R&D looked at a lot off tyres before they chose the MTR.

Have either of you driven a D3/4/RRS/FFRR with these tyres fitted? And not round some poncy LRE day where you could get a Ford KA round??

Ok, perhaps I'd better post a reminder that we like to keep things civil around here.

Except for road noise, surely? In the Top Trumps world of tyre choice, every tyre scores differently in each category.

Does that really matter, even if it is true? I wouldn't personally buy a set of MT's based on road noise.... You will always have to compromise.

Are you sure the 305/50R20 will fit without touching anything? They will be about two inches wider and two inches taller than the standard 255/60R18 tyres. Maybe they will, but I bet it will be close... I don't think the other two options will fit unless you have a Stihl saw ;)

The MTR is probably ideally suited to the G4 vehicles but since the G4 seemed to be mostly about carting mountain bikes and canoes around I wouldn't automatically assume that it needed a super dooper off road tyre :D
