Another thought ...

The Sp7's arrived this morning and they are a directional tyre.
Should this be noted as well?

Being directional (like the A032R) means having a left or right tyre set up for "optimal" use. (Limits tyre "rotation" and "spares" )
(I don't think they "explode" if put on the wrong way :lol: - but may degrade optimum handling performance. )


I could always put a little note on the bottom with a charater next to the name. Does it make that much of a difference though (tyre rotation), I only ever swap my tyres from front to back - never side to side as each side wears at the same rate on my car.

Can people please post when you rotate your tyres do you go front to back and/or side to side? Thanks

<edit> are the pictures of the tread big enough? I can quite easily resize the image to a larger size without even modifying the image (so don't be afraid to say if they are too small)

<edit2> god I'm a terrible speller

If the tread pattern is directional [edit: and fitted incorrectly], it wont displace water as effectively, leading to poor handling in the wet. In dry conditions I wouldn't imagine it'd affect handling too much; there's the same amount of rubber on the road at any given time..

The other danger with directional tyres (although I don't know if this is still an issue) when mounted backwards is the tread can strip away from the core. I have memories of this happening previously, but it could be an old wives tale :)

I think generally speaking a directional tyre is better than a non-direction. With non-directions generally being the cheapast anyways.

i think we probably dont need a seperate cheap and economy category, just make them all economy.

You can add Sime 165/60/12 Monza HR7 to your list, and it is rated as a good as Falken for long wearing, as for grip in the wet Im not sure as i only just got them.

Cost $70-90

Ok, I'll try to get another poll happening (wonder if I can change the current one? Obviously the colours are needed! 19-2) because someone put up the suggestion before (spaceboy?) about numbers to get more 'divisions' between the tyres.

I'll see what I can do, otherwise people can just post what they want (i.e. Words or numbers)

wasnt me :)

just to make things more complicated, how bout dividing the tyres by type rather than by brand?

The belt structure of (some?) directional tyres are designed to roll one way also. I got a car back from a service years ago when directional tyres were still a rarity and couldn't keep the car on the road over 80kph because the sparkplug jockey at the dealership had rotated the tyres all around the car. They can also cause excess rubbing of the belts against each other causing overheating and de-laminating.

BTW, how far is this chart going to go? I think it is a great idea and should be "stickied" when it's finished, but if you're going to designate which models are directional, do you also list which ones have an inside and outside edge to the tread - which aren't directional but must be fitted onto the rims a specific way? The dry and wet ratings should give anyone a good enough idea of what to look for before going out to shop for tyres. The more complex the chart gets the more work will be required to keep it up to date - I'd even get rid of the $ value and replace it with a rating as the cost can vary from one shop/city/state to another and will always increase with time. Just my $0.02

I will be dividing them into their "colors" at the end. It will still have the columns in the same order but they will be ordered in their colour group by their size.

I've decided that I'm not going to do the outside / directional bit - I don't think people will care that much to make a decision soley on those two attributes.

All this chart is for is to give people some idea of the grip and wear levels. I feel as though the price column is nessasary so people know around about how much $$$ they are up for for that performance in a tyre - there is heaps of variation but this is only intended as a guide. I'm sure some people would like to know if they are up for $250 or for $70 (depends on what kind of shopper you are).

Agree 100% Nick :D I really like the thumbnail too, for those who rate tyres on their hawwtness :lol:

Talking about Hawtness, that's why I bought my A032R's a month back - just because of the way they looked mmmmmm 8)

I'll apologise for the extremely long post now. Sorry.

I have put together one of each - one with numbers for the ratings and one with words for the ratings.

Tell me what you think.

Great work Nick, really helpful. Makes me want a set of D93Js all the more ;)

Can I suggest that whatever column you sort by, make that one the first? It's kinda confusing looking from left to right as it is.. plus, in its current form placing the manufacturer and model names together makes a bit more sense.

Am I making sense? :lol:
