Looking to get a set of 18s or 19s alloys pretty soon for the supra

I was down the pub Saturday night and my mate

"you want 19s on it,

255/30/19 rear

245/35/19 on the front?"

he said like the BMW setup,

I don't want an overly hard ride what kills my back lol

I know it's down to what the driver prefers but I would just like a few tips on what you guys are riding on?

And views on your ride in conclusion ie it's a bit too hard I'm looking at changing etc...

 

Cheers guys

I have 19's but recommend you go for 18's if your after more comfort.

 

The width and profile of the tyre will depend on how wide your wheels are

and getting the correct offset is also important

 

You should use this tyre calculator to get the correct profile to keep the rolling

radius close to o/e, http://www.etyres.co.uk/tyre-size-calculator.htm

 

Also heres a good offset calculator

OEM sizes - that's what the suspension is designed for.

 

But the most common aftermarket is a front 245/45/18 with a rear 265/40/18. As you increase wheel diameter you ruin the ride. It's all a trade off, what you gain from wider tyres, in grip, you lose in noise and wet handling (wide tyres aquaplane more because you have less contact patch pressure)

245/45/18 is a very large sidewall for the front.

can't go wrong with wider

 

Unless it rains.

 

I had the opportunity to test out my 255/35/18 and 315/35/17 Vredestein Sessanta tyres in severe wet weather last week (completely unplanned!) and they were outstanding.

 

I would choose these widths in this brand over the narrower Eagle F1 and Asymmetrics I used to run any day - wet or dry. However it was no accident I chose the Sessantas, they were a well informed choice. If you're "going wide" and think you'll use the car in the wet then be careful which tyre you choose.
