Tyre choice - can’t decide

Hi all.

I realise there are already many threads on tyre choice but I still need some advice. I have Dunlop Sp 9000 on 16” Lattice currently. They are pretty much on the limit, a quick look at the MOT checker (K974WRN) also shows they’ve been advisories for a couple of years now. I have some things I need to consider.
One: the 40 is my daily driver, not cosied away in a garage and only brought out in the dry, so will need something good in the wet. Two: the recommended size and size of the Dunlops are 225/55 r16. I’ve noticed there is an awful lot more choice of tyres when going up to 225/60. Will this be a dumb idea or not that much difference?
Three: I’m not concerned about sticking to a budget as am fairly confident my recently acquired 40 will be with me for a while. I love it! (Am also wanting the Andy bracket, also could do with new bushes and a few other bits and bobs but that’s another story).

Any advice is greatly appreciated.
Thanks
James

I can recommend Falken tyres, I put 55 profile on and they are brilliant, very grippy and quiet. Some Jaguar restorers are now fitting them as standard on the cars they work on.

Any good brand will be fine, including Falken. I have different brand every tyre change as I buy part worn tyres for mine and do a lot of miles every year and the ones that I liked most were michelin and kumho so far, currently running continentals and they are fine too.

Funny you mention more choice for 60s, I find it completely opposite with far more choice for 55s ;)

225/60/16 was a standard 40 tyres size for 1994 models.
But 16” Lattice where only fitted with 225/55/16.
My opinion is the 55 profile suits them far better than 60.
Jaguar knew what they were doing with that.
I would stick to the original size.
A choice is nice, but you only actually need one set.

A lot of people will choose based on “wet grip/ stopping distance”, as well as price.
I doubt there are any “terrible” tyres out there anymore these days? It’s such a competitive market, that I think all the quality manufacturers have to be on their A Game to survive.

How about saying which brands you have on your short list?
Personally I quote like Dunlop’s.

I had some free chinese knock offs on the rear some time ago, was wondering why they were free until first rain. They were absolutely hilarious in wet, could spin the rear in every puddle of water if I wanted to :lol:
I cant remember the name though, I think it started with aqua? :roll:

I should have been more clear- I meant of the quality/ known manufacturers. I think it’s clear you get what you pay for with tyres. The Chinese budget stuff is budget for a reason.
But amongst the established quality brands, I would think it’s quite competitive.

I have 225/60/16 tyres on lattices on mine, but they rub on the inner wheel arch on full steering lock. So definitely stick with 55s if you can.

Agreed, no more rubbing for me after I fitted 55’s.

Tyre size is nominal and varies between manufacturers and model of tyre. The only constant measurement between tyres is the 16" - some '225' tyres are wider than others. The width of the rim will also affect the width of the tyre. Another variable is the shape of the tyre and thus its tread width. Some tyres taper towards the tread, others have a virtually square sidewall. The variation in size and shape between particular makes and models of tyre is enough for some tyres to rub at full lock and others to clear the wheelwell, even when the tyres are nominally the same size.

The sensible thing is probably to put on 225/55 16 tyres which were recommended for the 8J wheel by Jaguar (7J had the recommendation of 225/60 16) - but I wanted to retain the extra cushioning of the 60 profile even though my car has 8J wheels. From research a couple of years back I reached the conclusion Michelin tyres have a nominally narrower width than average and a tapering profile - especially the Crossclimate. For this reason I put 225/60 16 Crossclimates on my Jag fitted with 8J BBS lattice wheels - they don't rub at full lock.

If you look closely the tapering nature of the tyre when compared to many others is visible in this photo:
