Tyre recommendations

[Nine One One]

I agree the Dunlop Sport Blu Graham recommends are £70 each, versus the £307.20 each for the CN36N (£1228.80 for four versus £280 for the Dunlops)
Horses for courses, but that is a £1,000 saving towards your respray/paint job, or say a suspension upgrade. To be honest, you can not drive faster than 60mph on normal public roads (Motorways are a straightish line most of the time). Will a normal driver actually notice the difference, or sooner keep the £1,000 towards something on their car????.

What is the actually EU efficiency rating on the CN36?

I put the Dunlops on my 911, can't fault them at all. I've used other 195/65x15 tyres in the past, and frankly can't tell the difference between the Dunlops and the CN36s. If I had a car like a 2,7RS, I'd go with the CN36s.

I am on my second set of Dunlop Sports Blu, right diameter to make the speedo accurate, A rating for wet grip and A rating for road noise.
About £70 each?

What sizes are you running?

[911hillclimber]

15 x 195 x 65 on 7" rims.

15 x 195 x 65 on 7" rims.

I had a 911 fitted with that size tyres 20 years ago (Pirelli P6000). The steering at parking speed was heavy as hell. The index load of that tyre size is way too high for the front axle.
Because of the bad experience, I tend to avoid that size at all costs.

[domtoni]

My car is fine, no issues.

20 years of 195/65 r15 on my car … past 8 years running continentals that I find great . Suspension set up by centre of gravity with these tyres fitted

I wi admit I’ve never had 185/70 on my car but whenever it comes to tyre replacements time I can’t stomach over £1k on tyres for this car

I'm curious about this, but I don't know what that means! What do you mean by index load, why is it too high for the axle and how did that make slow speed steering heavy? Sorry for the numpty questions!

195 has slightly wider footprint but same rolling diameter as 185/70

[911hillclimber]

That's interesting.
The steering at low speed is heavy, but loosens up over about 30 mph.
I have a 360 mm dia wheel mind, so that won't help.

I have 2 x 6" wide Cookies for the front, and will fit narrower tyres to those rims when the current tyres are too old (7 years?) to pass the MoT.

I have in my mind the 70 mph wobble could have been down to the bushes in the lower A arms moving, but iirc Jame has solid bushing.

[gridgway]

There isn't an age limit for the mot for cars Graham. Just condition. That's one thing I do know!

If the comment about indeed load meant that "fatter tyres are heavier to steer when they are rolling slowly" then I get that bit!

[911hillclimber]

Then my Dunlops look to be lasting a good while longer still.
Wonder where I got the 7 year rule from, ie tyres fail due to age above condition.

While I was chasing down my wobble a few years ago, I borrowed some 6" front Fuch rims with 185 Blockley tyres, steering weight seemed the same to me.

Wobble still there with these loan wheels...
Anyway, drives fine now for some reason, may be a different story in the Spring.

[gridgway]

I have 185 Blockleys. Very light and nice although I have a big steering wheel

Not with 185s, no.
