i know nothing

About tyres. Or rims for that matter.

 

I currently have 18" GT Nissan wheels.

 

The tyre sizes that are on it:

 

Front=225/45/18

Rear= 245/45/18

 

I have just bought some Rota GTR 18" wheels.

 

Front= ET25 8.5j

Rear = ET20 9.5j

 

What size tyres would fit the Rotas? The tyres from the GT wheels?

 

I have no idea if the J on the GT wheels is the same as the Rotas. I don't want them to look too stretched or the rears to look more stretched than the fronts.

 

Can anyone help out an imbecile in desperate need of some guidance.

 

Please feel free to be as condescending as you like.

 

Thank you in advance.

The '50's Rays are 8J front & 8.5J rear, so the 245/45 from the rear Rays will simply swap to the front Rotas.

 

 

That's it. That's the sum of my knowledge. I'm sure someone more helpful will be along shortly.

Ok for starters....please be consistent in the spelling of tyres

 

Tires are for those living in yankee-land! Ha ha!

DON'T put the rears from the 350z wheels on the fronts of the rotas. you'll have to run 275/45 on the rear to keep the tcs happy, which is all wrong.

 

id go for 245/40/18 on the front, and 275/40/18 on the rear with those new widths.

 

but then again, the new fronts are only half an inch wider, and the rears an inch wider - with the standard 45 profile tyres, you probably wouldnt notice that much stretch.

[Rock_Steady]

I see. So, it's true that the Rotas are wider than the standard GT wheels.

 

It sounds like if I just slapped on the tyres from the standards to the Rotas, the rear may look more stretched than the fronts.

that's what your tyre will look like - 245 on a 9.5j

I ran 235/45/18 on the front and 255/40/18 on the rear with no problems

below is with 245/45 on the rear

Unless it's on 4chan, then the world is just doomed.

marginally - to the tune of 6mm a side. just swapping the tyres would certainly be the cheapest way of doing it. how much tread is left? if your tyres have still got plenty of life in them then just swap them over and see how they look. then if you dont like the look put wider tyres on when you get new ones.

[Rock_Steady]

There's loads of tread left on the tyres I've got on the GT wheels. I just don't want to have such a wide gap between them and the arches. Having said that, I plan to drop it in the next few months.

 

I think you may have made up my mind for me Brillo my man.

[Ekona]

I'd just swap the tyres straight over, personally.

[Rock_Steady]

I think i'm going to swap the front ones straight over and get some new rears. 255/40/18

unless this buggers up the tcs?

[Ekona]

It could, yes. Unlikely, but not impossible.

 

It will also cause more understeer.

[Rock_Steady]

Blast "n" buggery then, I'll just swap the sods over and go from there.

My Michelin pilot thingys, with 245/45/18 on 9.5j look a lot more stretched than your grund

 

Your oem tyres Will fit and look fine

 

I ran the stock sizes on my lmgt4 that where 8.5 front 9.5 rear was fine
