235/85/16 on RV6, do they fit?

Hi, im looking to get some wider tyres on the standard rv6 rims, the extra height of 235/85 sounds good but does anyone know if they will rub on the wheel arches? I realise they will throw the speedo out but i can live with that. Keith

I too have an RV but I went up to a 16x7 rim and put on some 265/70/16 which clear the guards no worries. It handles & looks awesome now with a bit bigger feet.
I know this doesnt answer you question but it may be another option if the size you mentioned does not fit.
I picked up 5 GXL prado rims in perfect condition off Ebay for $400.00 delivered to Brisbane from Sydney. I was lucky with the tyres as my boss at work was upgrading his 16x7's up to a new set of coopers so I paid $100.00 for his set of 5 Pirelli Scorpion ST's which had done about 12000 km's but the spare was still unused.
Good luck and let us know if the size you mentioned fits if you do go with that option.
Cheers.

Hi Keith

I have seen a few RV model prados in Perth with 235/85's on the standard 6 inch RV wheels. I nearly went this way myself, but ended up getting some nice 16x7 alloys and putting 265/75's on them. If you put 235/85's on your rims I think you will need a suspension lift or they will rub. The front will likely rub on the mud flap protrusion on full lock and compression, and the rears might rub on the inside of the guards on full flex.

The advantage of going to the wider rims is that the track is made wider which gives the prado a more stable feel. Also the 75 series tyres won't squirm as much as the 85 series tyres.

But having said all this, I reckon RV prados look pretty good with 235/85's on their standard rims and the ground clearance will be impressive. Another advantage is that you wont need flares if you go this way.

Cheers

rv tyres

Thanks for the reply Mark, I think you are right that 235/85/16 might be a bit big for the wheel arches. I saw a second hand set in the Quokka for $50 each with 1/4 inch tread left and it got me thinking. I am now leaning towards what you did and get a set of alloy 16x7 rims. Costly at first but better in the long term. It just gives better tyre options in the end. Did you have to fit flares on yours? I was sitting behind a 80 series cruiser at the lights the other day and the tyres were sticking out about an inch from the body with no flares, risky i reckon if you get pulled over.

Hi Keith

I haven't put flares on yet because I'm having trouble getting some. Toyota unfortunately don't have any more of the factory RV fender flares left. That really only leaves TJM or FRP which are a bit pricey and I haven't decided if I like the look of them yet :roll: My tyres do protrude slightly but touch wood, I haven't had any trouble from the cops yet.

Cheers

Flares

Mark, on another post in here there was a link to some DIY flares from Bushman, i think it was ,and they looked OK. Said they had strong wire along the outside to stop sagging. I think we've all seen those crappy plastic ones that warp. I also had a good look at an RV with GXL rims and 265/70 's on, in a shop carpark, and they looked great. I like the idea of widening the track for better stability/handling. Did you notice an increase in fuel use with the bigger tyres? Mines on gas anyway, and is reasonably cheap to run, but Prados arent great on fuel, especially after having a gas Hilux. Keith

Hi Keith

You will find the bigger tyres do use a bit more fuel. Maybe around 10-15%. Part of this is due to the increased rolling resistance of wider tyres and part is due to the increase to the effective gearing from the tyres being taller. I guess wind resistance also increases as the car gets taller which would be a slight factor as well.

My Prado has different diff gearing to normal which has caused the car to be slightly undergeared which means I get very close to the original fuel consumption figures.

Cheers
