(matching trailer) However my issue has been load rated tyres.In the factory 245/35/19 I can only get a 93rating (650kg). Local Bob Jane guy said they upped the Aspect ratio and fitted 245/40/19, 98(750) to a GS ute a while ago and haven't had any clearance issues so far. Speedo is 3.8% off. Also thinking possibly 255/40/19, 100(800kg), 5% off.Specifications for the One Tonner say max rear axle load is 1700kg so if I got to 1600kg worth of tyre rating that's enough for me.I also what the bigger numbers so I can register my trailer with a higher Load capacity.So whos done this before and had experience?How does upsizing affect acceleration, drag times, launching, handeling, cruising revs etc? Considering the same brand/pattern tyres.Also how would I find out the weight rating of the rim itself? The local parts department potatoes aren't that helpful, they couldn't even find my wheels on their system & said they must be an aftermarket option.http://www.tyresizecalculator.com/tyre-wheel-calculators/tire-size-calculator-tire-dimensionshttp://www.bobjane.com.au/info/load-index-speed-symbol/ Link to comment Share on other sites More sharing options...

You will still get defect for being under the load rating As for driving it will be geared up slightly. Not a massive problem for most people. Look at all the staggered 20" rim guys running 275/30 rears and 245/30 fronts. Which are already massive compared to the stock 235/45/17 wheels.

There's random codes stamped in the back but couldn't figure out if any of them meant anything. It's a turbo FG so only rated for 500kg payload, I often carry more than that though Which is why I'm chasing better Tyre ratings.Sent from my 0PJA10 using Tapatalk Link to comment Share on other sites More sharing options...

Alloy wheels can't be widened can they?Sent from my 0PJA10 using Tapatalk Link to comment Share on other sites More sharing options...
