Tyre sizes 245/265

[rvT350]

I currently have 235/255 tyres on my T350 but I'm needing a new set of rubber.

I'm thinking of changing to 245 front and 265 rear as this seems to give me a lot more choice for semi slicks.

Has anybody run these sizes on 18" spider rims and how did it effect the handling characteristics of the car?

THANKS

I know the 265 go on the back as I have seen it done but not sure about the 245 if honest as it was on a sag and they are 255 on the front.

I'm amazed you got 235 to fit the front 225 on mine only just worked (it rubbed)
245 to me seems way too wide

I was thinking the same. Are there more people on 235 up front without modifacations to make it fit?

Hi

I run Toyo R1R's 225/40/18 on the front and 255/35/18 on the rear.

They are actually 230mm wide and fit the spider much better. They do catch slightly under the arch but not very often. I do have nitrons and have raised the ride height a little to compensate.

Cheers

p.s. stick like st to a blanket!

225/40/18 on the front is a really postive change to the handling I found on the T350. That extra 5% of sidewall just makes the car so much less twitchy on our very uneven UK roads.

Richie the max size you should be putting on a 8.5" spider is 255 you need to go up to a 9" wide to get the 265 on to safely keep it on the rim under cornering!

Those are the sizes I too am going to be running using federal 595 rs-r

Thanks for the replies.

I think I will be going for 225/40/18 front and 255/35/18 rear in KUMHO V70A ECSTA medium compound semi slicks. Toyo R888 and Yoko AO48 availability is terrible at the moment and the Kumhos are supposedly stickier and are cheaper.

So those tyres, 3.91:1 final drive and quaife LSD should make for some good improvements in acceleration and getting the power on the road.

I've got 225/265 on SP12s. I don't think you can go wider than 255 on spiders.

Does cause some rubbing issues if you have standard suspension.

I'll be looking for some front tyres for my T350 soon and want to go 225/40/18,be interesting to know how you get on if the catch.
I had the kumho v70 on my sunbeam lotus they were fantastic so much grip.

225/40/18s were fine on my T350 with the odd wheel arch scrub on full lock when parking. Much better drive than 225/35/18s imo.

Lotus Sunbeam - nice car - my best mate had one of those when we were in our twenties, black with silver stripe - loved it. He did to !

I run exactly the same tires and sizes and I agree (especially with the p.s.) although I still have the standard shocks I have no issue at all except when one of my heavier mates gets in as a passanger :-)

Any wider would not be possible for me unless I have the inside of the arches a bit widened...

I loved my Sunbeam Lotus my wife would'nt go in it.

Any one tried the federal 595 rsr or yokohama ad08?
