Thread: 15 inch rims and 35-37 inch tyres- any issues???

Depends on the final use - if for looks go 16" if for rock hopping go 15" as they provide a bigger cussion between you and the rocks.

For looks???

Final use is for all out muddy, rocky, whatever terrain action...

Thanks for the reply. It's a weekend machine, and gets locked up otherwise, so looks aren't a big deal.

I just wondered if the 15's will fit ok around the discs, etc.

Don't know definitively, though early rangies and discos came out with 15"

I would so like to not ask this, but I don't really understand the "Which Tyre" threads just yet.

I wen't 4WDing this weekend, up near Moore River. My Disco is a 95 model with standard tyres and rims. Unfortunately, I got bogged twice, and thought I was going to have to leave the car on the beach.

I can't believe how much softer the sand is north of Perth as opposed to down south, but anyway.

I would like better sand traction. I don't have a lift kit, and only the standard rims that came with the vehicle.

Can someone tell me:
(1) Will these tyres perform better on beach sand?
(2) Will they fit my vehicle ok.
(3) If some cutting is required is it something I can do?

I only use the Disco for 4Wding or getting to 4WD places, so day to day traffic type issues are not a concern.

Thanks in advance

15" rims fit OK on Disco 1s - had them on both my D1s.

Your not wrong about how soft the sand North of Perth is, I've been down to 10PSI on standard tyres up there and it was nerve racking. Its softer than any sand I've driven on over east or South west. The south west is probably the best sand driving conditions IMHO. (makes me wish I was back there - plug for Esperance)

AT are better because you dont have traction anyway, mudders just dig in.

Sorry, I meant to say will they fit on the standard rims. I don't have any money for new rims right now.

@Ian_T: Any specific ATs you recommend?

A 33 inch tyre works well on a 15 inch rim because you have enough sidewall to give you flex as well as being able to maintain good road manners.

I ran 35's on my RRC and then D1 for years on 16 inch rims and never noticed that I was being left behind by vehicles running 15's. Keeping in mind most super aggressive tyres at 35 inches + are bias ply and not radials I would run a 16 inch rim as you have too much flex in the sidewall to get accurate steering. At those sizes you have to really adjust the way you drive to suit the tyres both on road and in the bush.

Re sand driving a wider tyre is better and you need to deflate your pressures to help you float on top of the sand. However a taller tire will also give you a greater footprint when deflated. The more tire you have contacting the surface the better. An dont spin the wheels unless you want to end up in China.
