Dolium 45l auxiliary fuel tank and bigger tyres

[n plus one]

Does anyone know if the Dolium rhs rear quarter tank has been changed to allow the figment of larger than standard tyres?

I understand that those running 255/85 had issues previously when the suspension bottomed but believe the tank design may have been modified?

I'm currently running 255/85 tyres and may yet go to 35s (although this would likely involved dropping the bumpstops so would probably be analogous to 255/85s with standard bump stops).

Anyone got any info, experiences,etc.

Thinking about moving away from my rear long range tank for rock crawling reasons :twisted:

I can't help, but I may be interested in the LR tank if you sell it.

Not really, I'm planning on fitting them anyway but still want more capacity :D

I am fairly sure this has been discussed before and from memory was around 255/85/17s. I am fairly certain they fit fine. I would envisage if you go 35s you would be thinking a lift kit as well, as that will give a bit more clearance.
I have one in mine but I am only running 235/85/16s. There is more than ample gap for this and mine sits well within the rear quarter by about 50mm from the leading edge of the guard not including the flare which it sits very clear of.

I think you mean the Front Runner tank. I have one of these which I have run with 255/85/16 KM2 tyres. My tank was purchased new in June 2013.

It will rub, but not much. Enough to take the paint off... There are 2 things that I do to minimise the rubbing:


There's about 5mm of lattitue in the mounting position. Ensure that the tank is mounted as far back as possible.
Put your most worn tyre in the rear driver's side position.


You mentioned an extended bump stop - that might help (it certainly can't make it worse!), but I haven't tried it with the 255/85/16 tyres.

As for 35" tyres, forget it - it ain't gunna happen!

Cheers, that's not encouraging news!

Yep, I'm talking about the Front Runner tank - I think Dolium is the Aussie importer, not actually sure who is the manufacturer (possibly Boab?).

There's a rumour that the tank has been slightly re shaped to take bigger tyres (not sure when though) but this is proving hard to confirm.

I'm just trying to figure out if a reshape plus extended bump stops might make 35s doable.

The rumour that they'd (already) been redesigned was around when I bought mine. I suggest that you contact Front Runner directly to confirm if/when a redesign occurred.

As for 35's... My current config on that vehicle is a 3" lift with HD springs (way too stiff), extended bump stops and 285/75/16 (approx 33") tyres. With this setup the tyres rub similarly to the 255/85/16 with standard suspension, so 35s are simply not going to work.

I have 35s on my other 110. It's a change that has consequences. If you're going to do it right then there's a LOT to consider when putting on 35s. Plus, you've got to live with them once you've done it. They're great for rock crawling but there's no way I'll be putting them on my touring 110... And touring would be the reason for putting in a 45L aux tank.

BTW, I'm really happy with the Front Runner tank. It's a great no fuss "install & forget" product, but make sure that your feeder line isn't unnecessarily exposed.

Cheers mate, I think that answers it then!

I'm quite torn around the 35s - I've followed the build of your Puma on 33s, do you have s similar thread for your 110 on 35s. I'd like to get a sense of the mods/issues you've done/had.

Cheers,

Luke

LukeI don't have a similar thread for that car because (happily!) I bought it will all modifications already done. The previous owner did a very thorough end-to-end job.

Ok looking at some of what has been said, not sure if mine is normal but maybe I appear to have my tank sitting back a bit further than standard. I should highlight in my first reply I had a typo and typed 17 when should have been 16. They are Front Runner tanks supplied by Dolium in WA and I think Mulgo supplies them as well.
I am not home at present but I would say I have over 75mm gap between tyres and tank. Can measure when I get home if you remind me next Wednesday. I know I can get my hand in a fist in between horizontally easily. I am fairly sure I gained a lot more than 5mm over what they showed when fitting mine too.
I would say you would get 33" tyres without too many dramas and I am sure there was previous discussion here with people having done so, with minimal rubbing on full compression of the suspension.
I am also happy if you know anyone near me that wants to put their 33" tyre on to check clearances. I don't have any 285/75R16s to try.
Running 235/85R/16s I have never had it rub or even come close. I reckon even with my 50mm lift it would it would hit the flare before it would even go close to the tank.
Having said that you would need to know the gap at full compression of the spring, not sitting normally in the driveway.
There is only around 25mm or an inch difference between mine and 33" obviously.
235/85R/16 Rolling Dia 774.6mm or approx. 32"
235/85R/17 Rolling Dia 800mm approx. 33"
255/85R/16 Rolling Dia 805.9mm approx. 33"
285/75R/16 Rolling Dia 800mm approx. 33"
35" Rolling Dia 825.4 approx.
35"s would be an unlikely fit and would certainly rub, but you may get away with 33"s.
depending on what you do you may need to think about trimming flares and guards anyway.
These could all be +- 5% depending on tread as well.
