Hi all,

I know there's a little literature on this site regarding rims and sizes allowable for Hilux splits, but would like clarification.

I currently sport a set of 205R16 Dunlop Roadgripper S (which wear way too quick) and they need replacing.

I have read that these rims will also take 225/75R16 tyres. Also that the 205R16 is akin to the 205/80r16, so my options are opening up wrt tyre choice.

Thing is the Hilux splits are 16x5.50" rims and the specs for the 225/75R16 state a 6.0" rim is required The local tyre bloke says that they're a fit, though i'm concerned about 0.5" rim width diff.

And can anyone validate the 205/80r16 as a good fit for the rim?

Is this right??

I don't want to order tyres to find out I need to get new rims too, or to suffer tyre failure...

Thanks.

Joshua.

Gday Joshua
Read the tyre plaque on your vehicle , that's what you legally are aloud to use.

Thanks MUZBRY, but I think that that's not all you can can legally do?

Most Hiluxs I know are not fitted with their orignial split rims. Many have 31x10.5s or even 33s at the extreme.

The 205/80r16s are essentially the same as the originals, so I doubt they'd be illegal as a result of nomenclature.

There is some information on this linkhttp://www.dunlop.ca/care/widthRatio.html regarding rim widths and what can happen if they are too wide or narrow for the tyre.

You may not gain very much in extra mileage with a 205/80 or a 225/75 no matter what brand they are. The 205/80 is the same diameter as a 205R while the 225 is only about 10 mm larger. Both are doing a lot more turns per kilometre than the much larger sizes that are constantly being discussed on 4wd sites. The larger tyres often have deeper treads as well. This usually adds up to more ks but they cost a lot more than a 205. You would have to work out the cost per k for each size to see how they compare.

Thanks splits, good link. The reason for trying a different size it to broaden my choices. In the standard 205R16, there aren't too many to choose from, not here anyway. There are more 225s about, such as the Goodyear Wrangler DuraTrack.

I sold the 31x10.5s that came with my Hilux. The split rims handle so much better off road, especially the corrugations.

G'day Josh,
I run BF Goodrich AT's 205R16 on my Hilux split rims & find them much better than the Roadgrippers. I must warn you though DO NOT settle for the junk tubes that most tyre places carry these days. I do a quite a bit of sand work & if you run them at low pressure you will more than likely blow a tube big time when you go back to road pressures.
You will probably have to order them in but pay more & get Michelin tubes.

Most people are not a fan of split rims but I do some remote travel & find it easier to do my own puncture repairs with the splits.

Cheers
Stu

Thanks Stu.

Looking for inner tubes, where do you source yours? I'm all for better quality ones, though the local bloke uses a brand called tyre tube or something. I was hoping to get Dunlops or indeed Michelins. Can't find many and not sure what size I need? Any ideas of getting them online or name of a supplier?

Thanks.

Joshua.

I got the TYREPLUS store in my area to get me the Michelin tubes. Only took him a few days to get them in. Standard stock tubes most of these places carry are garbage. Just pick up a cheapie in one hand & a quality tube in the other & you will find a significant weight difference between the two.
As for the size you need to get the appropriate size that suits the tyre size you buy.

Cheers

its even worse than that, its very hard to get a patch to stick to those cheap tubes and really you would replace not repair - something to do with the cheap butyl synthetic rubber composition

Thanks. I did note realise that about the patches not sticking to the cheap tubes. Probably because every cheapy I have seen has totally disintegrated & is betond repair anyway!

Joshua,
The 225/75R16 is a very common replacement on the Hilux.
But there are good reasons why the Hilux is no longer available with split rims.
Consider the cost of a second hand Hilux rim is not much more than the cost of a quality tube. You will get more miles out of a tubeless tyre on a tubeless rim because they don't run as warm as a tube tyre on a splittie. You won't get any tube failures either!

So if I were you, I'd bite the bullet and get yourself a set of 6" 90series Prado or Hilux tubeless rims and if you want the same diameter tyre, buy the 225/75R16. If you want a taller tyre, on a 6" rim, you'd need the 215/85R16 (an uncommon size that usually needs a brand like Toyo) or if you want to stuff up the gearing and speedo go the common 235/85R16 which is 60mm greater diameter and is technically illegal in every state.

And when it comes to fixing tyres, you'll do it less often with tubeless. I also find tubeless easier to repair than splits. Splits are easy to reassemble and can be reinflated with a bike pump but can be a big effort to get off the rim. But tubeless can be repaired with a plug which is what I always do first.

Cheers

Thanks Phil,

I see your logic, in fact it makes sense. I had looked at the newer HiLux rims, just baulked as I wasn't sure how an LN167 would look with those rims - maybe a bit of place?

The beauty of the splits, I see, is the ability to swap them out with some hand tools - not that I have had to, yet. But it's simple when care is taken.

Thanks for the input - real food for thought.

Joshua.
