Sometimes it doesn't work out

Over the weekend I tried to save some money. The car we recently bought for my lovely girlfriend needed new tires. We knew that when we bought it though so no shocks there. What I did realize though is that I have a car with tires that still have a little tread on them on a car in a paddock that doesn't need tires that are legal on the road so I thought I'd try and put those wheels on the Mazda.
This is one of the stock wheels on the Mazda, They are a 165/70R13. So they are 165mm wide at the tread and have sidewalls that are 70% of that width. The tires on the Pulsar are a 195/50R15 so 195mm wide with a sidewall 50% of that width. That means that they are lower profile and are less likely to roll over themselves during a corner; but we aren't going to be doing that sort of cornering in this car.

Being that they are a bit wider I wasn't sure if they would fit. But in the name of not wasting a set of tires with a decent bit of tread left on them I decided to give it a go anyway.

Here they are in situ. Let's do this the easy way.
A rattle gun. With proper impact bits even. I learned my lesson after wrecking a 1/2" drive to 1/4" drive adapter with this thing. Get the proper impact bits. And so far I haven't wanted to use this driver on a bolt other than the sizes in this set so for most cases a basic set like this is plenty ample.

I did however make the mistake of undoing all of the wheels in one go. Then trying to take them off one at a time. If I was doing this on a hoist that wouldn't be a problem. But if the car is sitting on it's wheels then as you jack it it will move a surprising amount and you want all of the other wheels to be secure as it's shifting to stop it falling over.

This was the only jack I had with me. It's just the one that came with my Rodeo ute and was doing fine. Until it wasn't. All of a sudden it just wouldn't move either way. I'm not sure what happened but it worked fine the next day so it might've just gotten cold, or just needed a bit of rattling around in the toolbox on the back of the ute.
Luckily there have been a couple of paddock bashers through this paddock and we have usually taken the jacks out. Either because we needed to use them, or we wanted one less loose thing in the car with us. I managed to find this one down near where some of these cars have been kept in the past. It even had a driver on it so I could put a socket on there and jack up the car with the rattle gun. Very easy way of doing it.

So this is why they say to do this on level ground? That black dot is the last tire. It didn't fall over when I dropped it after taking it off. Then I couldn't kick it over to stop it so I just let it go. It finished not far from this picture so I just picked it up on my way out.

Here we are. That's a pretty tight fit. Overall these wheels have a slightly larger diameter. But within what is allowed by law so it's only a case of will they hit anything?
Moment of truth here...
And a no go. Unfortunately we don't just drive in a straight line so these wheels didn't fit.

We had a new set put on today for about $400. Not going to take food off the table, but it would've been nice to be able to put that off for a few weeks even.

But that's something to remember. As much as I do eventually get just about everything working how I want it. Sometimes it just isn't going to happen and the time and effort you have invested could probably have been better served elsewhere. But this was only a bit of fun and the results either way was very much more about if I could do it, rather than it being critical.
