Anyone interested in temporary tyre swapping?

I'm curious to see how my L Series would run on stock size tyres, or at least a size much closer to stock. I would prefer to try them for the time it takes me to start at a full tank and empty the tank. I want to compare acceleration (seat-of-the-pants feeling... hard to actually see it while driving) and to see what kind of difference it makes in fuel consumption. If my L Series is like taza's, I can probably gain 80-120 km distance to empty.

I'm sure there are probably a few members with similar interests,
like some with stock tyres and would like to try out 14" wheels with 185 width tyres.

If you were passing through Canberra I'd be happy to lend a set of 175/75R13's. But I don't have the time to deliver.

The tyre change is also gonna affect the number of kms you record with speedo odo. You go smaller tyre you are gonna record more km for same distance than larger tyres gonna clock up for you , confuse your issue

Not sure about that...

Most here have accepted a NA EA82 will achieve 'ok-ish' economy. In a 20+ year old car, there is little point fussing about it once you have it running the best it can (tune, oil, PULP etc).

From there the 'savings' are not if it uses 9.6 or 10.2lt/100, but that it has little value, and can be fixed as a DYI with recycled parts, and it makes us feels good keeping a piece of Japanese motoring history alive.

Why do you think we swap to EJs?! (or for those like a 'challenge' EA82ts)

I put bigger OB rims and tyres on my 92 Liberty. It didn't feel sluggish but... my economy around town got worse went from 10.5l/100km to 12.2l/100km and yes I compensated for the larger diameter and distance covered in my calculations. The larger OB rims and tyres also weighed 1.4kg(each) more than the standard rims and tyres, so I'm not sure if it was the extra weight that caused the increase in fuel consumption or the extra inertia required to turn the larger diameter.
The other thing that happened was my engine started pinging under load going up slight inclines at around 2600 rpm
I've gone back to standard now and all is good.

I think it's both.

My 2008 Civic back in Canada,
I always gain 7+% in distance to empty on my winter tyres 195/65R-15 mounted on light alloy rims
VS. my high-performance tread summer tyres at 205/55R-16 and factory (heavy?) alloys
(each wheel + tyre combo weighs 6lbs more)
My car drives like it's 200-400 lbs lighter or 2 adult passengers less (2850 lb unloaded) on winter tyres.
Not counting inertia, I save a total of 24lbs or about 11 kg.
Funny thing is my winter tyres are actually a few millimetres larger in diameter.

Gripwise, the summer tyres are amazing and I'm able to put nearly 50% higher g-force while cornering.

I just think a set of stock wheels and tyres might be nice when I want to just do a long road trip and don't plan to do any more than light offroading; basic gravel roads to a campground?
