Do D4 19" rims fit MY11/MY12 TDV8?

[Graeme]

Does anyone know if D4 19" rims will fit these vehicles?

[CSBrisie]

Answer somewhere in here I suspect Graeme...

Thanks - lots of info but I gave-up before finding the answer so might try to arrange a test although only limited tyre options for 19" anyway. If we get to upgrade vehicles then I'd see how 20s go first.

[Graeme]

The 19" rims from my 3.0 D4 do fit the 4.4 TDV8. I didn't buy a cheap set on ebay a few days ago because I didn't know at that time that they would fit and I didn't know that the oversize 20" tyres that I was considering would not fit in the boot alongside my fridge, only discovering that today.

Graeme, well done! Helps to have both vehicles available for test at the same place.can you post a pick of which 19" wheel it is please?

They are the original rims from my MY10 3.0 in this picture. At this stage they're only fitted to see to what extent the harshness of the original 20" tyres is reduced when using 255/55R19 fitted with Hankook RF10 with their slightly taller sidewalls. If not sufficient then I expect to fit Nitto G2s in 275/55R20 that will have more sidewall height again.

I know we have discussed it in the past but the 275/55R20 on my car are sublime as far as taking the sharp edges from the air suspension. My wife thinks I am crazy as the car rode like a Bentley with the 255/50R20 as standard, but it is just like a balloon now, no concept of harshness at all. Now, as a tyre guy, (see number plate), this result is about tyre choice. If I had gone for a LT spect tyre with a firmer side wall, I would not have got the ride benefits I now have. I don't tow a huge caravan like Chris does, I sometimes tow a small trailer but most of my driving is long haul, reasonably quick stuff over country roads or dirt roads in mining areas. I have rarely suffered punctures in this environment and so grip and comfort over long distance are my priorities. The 275/55R20 size is the perfect combination for me. I hate that I cannot get a spare in my wheel well in the boot but I figure I can limp the car on the smaller standard spare if necessary and also let some pressure out of the other three tyres to assist with the gearing difference. I would be interested in 19's if it meant I could run the higher sidewall, better traction tyres and still get a spare in the wheel well in the boot..........interesting conundrum.
Thanks again,

Your comments about the ride on your 275/55s are very appreciated.

It was only a short run to the village and back this morning on mostly a now sloppy driveway and gravel lane but the ride improvements are promising. The Hankooks were superb in the slush, without any sound of TC activation even uphill. The RRV steers beautifully on the muddy lane whereas the D4 always wanted to pull left or right through the mud, even with these same wheels and tyres.

I'll still go to the Nittos if I think the ride on bitumen needs to be improved with the hope that I'll be able to squeeze the large spare in the boot somehow. I suspect that the fridge set at slight angle would provide just enough space. The fridge would have to be removed to extract the tyre but that's required to get to the jack and for the standard spare anyway. The Nittos are preferred for their more open tread than the ATRs for slush but not LT with possible harsher ride, probable worse noise and fuel consumption.

Edit: Good point about the std size spare. It gets used very infrequently and for relatively short distances. Faults generated by ABS from different wheel speeds whilst the steering is straight that cause the suspension to lower can be overcome by removing the 20A fuse 5 in the rear panel and probably the 5A suspension fuse too to avoid constant messages. However a full size spare would be necessary for an off-road trip for which a roof-rack might be fitted for other reasons anyway. Almost a case for 6 rims so that the large spare gets worn along with the other 4, which also caters for the possible short-term unavailability of the particular tyre.

Have you looked at 275/55/19s ? They are about half way between standard size and 275/55/20s. 275/55/20s must be huge as 285/60/18s looks big compared to 255/55/19s.

Unfortunately the 275/55/19s are less common than standard 19s and have an ordinary load rating.

[Graeme]

Nothing much available in ATs in 275/55R19 in Oz and even if importing still not much available.

I would fit the 275/55 because of their taller sidewalls and narrower tread than 285/50 - probably very close to 255/50 tread width. Yes they look large but I don't think the size looks too unusual on the various pictures I've seen given the large guard wheel openings of these vehicles. There's more than 1" clearance on the bump-stops with 30" tyres so should still be able to move if the suspension spits the dummy.

Not good to load-up diffs too much with a 2" smaller OD tyre on 1 side if using a 30" spare, so when pulling a heavy van a same sized spare would be needed. I'm always on light throttle if turning sharply in my loaded semi to look after the diffs.

Graeme, I assume that if the 19's fit the GOE 18 inch wheels would fit. My 285x60 R18 tyres ride way better than the 255x55 R19 tyres.

[Graeme]

No, the GOE rims don't fit over the TDV8 / SC brakes. They do fit over the petrol V8 brakes (same as 3.0 D4) so the callipers and discs would need to be changed. The V8 discs are the same as the D4. I understand that 18" RR rims fit over the rear brakes and the clearance with the 19" suggest they would. A front brake change is my last resort fix.

[RR44TDV8]

275/55/20s must be huge as 285/60/18s looks big compared to 255/55/19s.

here are the 275/55R20 at normal ride height.

G'day Grant
I hope you don't think I wasn't having a go. I have a single 285/60/18 that came with a GOE rim and it looks tall in comparison to a standard 255/55/19. So I was wondering about how drive shafts, cvs and diffs cope in cross axle situations with the additional resistance of bigger tyres. Admittedly it looks fairly normal against my 285/65/16s on the 110.

After my tranny mishap I've started thinking about how a broken shaft, cv or diff could be a show stopper in a very inaccessible location.

The above should read 235/85/16 on my 110.

Looking back through some old tyre threads here and elsewhere I see plenty plenty have used 275/55/20s, and some have used 285/50/20 & 275/65/18 which are bigger again. So ignore my comments above.

[Jetfisher]

I am considring options for 20 inch tyres for my 2010 tdV8 RRS...I have lots of information on tyre choices... but can anyone tell me the maximum size 20" wheel plus tyre (so largest possible diameter) that fits in the wheel well under the car?

[rar110]

There is a similar thread in the D3/D4/RRS section. It sounds like 285/50/20 is the biggest that will work.
