Anyone have experience running 245 width tyres on an 8J rim?

[Spetznaaz]

Hi guys, haven't been on here since the beginning of the pandemic, got so much on my car that needs fixing!

I want to put on 4 winter tyres as my summer ones are nearly at the limit. I'm currently running 235/40/R18 on Le Mans wheels (Look like these: https://i.ebayimg.com/00/s/MTAyNFg3Njg=/z/MeIAAOSwCXRch23p/$_86.JPG ) which are stock for my model.

I'm not 100 percent on the width, i THINK they are 8J but my alloys have been refurbished so much you can't actually read the width anymore, with the spare at least anyway. I know these wheels come in a 7.5J an 8J and possibly an 8.5 and 9J in the 19" at least.

I find there are a lot more second hand tyres (can't afford brand new) in 245's. Found some good Continental TS850P's for a decent price.

Has anyone experience of having 245's on this car and/or any 8J rim?

Any problems with handling or rubbing?

Cheers :)

Look up giga tires and tire easy. They are both online. They price match but one of them offers free shipping.

I used the free shipping one and they price matched the other site to i saved double.

Ive ran Continental, and General winter tires and both were supreme.

Im trying out hankooks this time around and i got them for cheap.

The coupon discount is the price match.

im not sure i would run 245 in winter, but then again im not sure the UK even has a real winter ;)

A wider tire is never worse for traction except in packed snow or ice. For normal winter driving, with relatively clear roads a wider tire is still going to give you more traction. Frankly, though, a 10mm narrower/wider tire is going to make any difference whatsoever. For winters, pick the cheaper size that still reasonably fits the wheel.

I run 225/40 18s Nokians for winter because I got a solid deal on a barely used set from a friend. I would have gotten them if they were 235 or 245 (assuming a close-to-stock radius). This "narrower is better" advice isn't wrong, its just missing the context for how much more narrow the tire needs to be to make an actual, noticeable difference.

TL;DR? If you drive on maintained roads then get whatever size that fits and is cheaper. If you have specific needs for max extreme condition traction, maybe go narrower if it makes sense.

thats why i wondered what " winter" means to him ...

a nice winter day where i live

[Charles.waite]

Yup. My impression of Uk winters is that there’s a lot of really cold rain. Sorta like Seattle. We usually get snow once or twice a winter. And it lasts for a day, maybe two.

[EvolutionArmory]

Offset and rideheight will be a big factor wether on not you should run 245’s. On a ET 48, 245’s rubbed the uprights on my car. With a 10mm spacer, I rubbed the front fenders but I’m lowered. If your wheels are a 42 or 43 offset stock wheel, it probably won’t rub.

The short answer is you should probably run a 235 or even a 225.

bastard ,.. !! :)

but then again microdrifts are kinda fun ...

Thanks for the replies guys.

Yeah our winter's here are nothing compared to what you guys gets in the U.S but when it does snow the country comes to a standstill because everyone's got summer tyres on lol. From my understanding winter tyres are not just for snow but whenever the temperature is below 7C which is between November and March here i think. It also rains non-stop.

Our roads here are definitely not well maintained. The reason i was thinking about getting 245's was mainly because there are a lot more second hand ones available on eBay than 235's but i do also really like the aesthetics of a wider tyre. I am concerned about rubbing if i put 245's on there (in summer i would like to anyway) plus i had a thought, if i get a puncture i couldn't use the 235 spare wheel.

When i get a chance i will take a wheel off and see if i can find the offset and width of my rims.

Edit - Also i'm not sure how much my car is lowered compared to the stock A4. It is an S line Special Edition which i think was only sold in Europe and is slightly lower than the s line.

you are correct, winter tyres are more about stickiness at temps below 7C than anything .. here in Canada it gets a bit colder than that even lol.

getting heat into my HP summers on my Porsche even now is tricky. makes them a bit greasy.

[Charles.waite]

Yea winter tires are for cold temps just as much as they're for snow. I commute in mine in the winter because my summer turn into hockey pucks in the winter. I will say the cornering limits drop significantly even in the dry with the Hakkas but they're very surefooted on cold days and can EASILY handle the worst weather we get up here. Seattle basically shuts down when there is snow, but its great to be able to pop out to the store without concern for getting stuck or needing to drive super carefully.

[EvolutionArmory]

Did you check the offset yet? It makes a huge difference as to being able to run a 245 tire.

What you should really do is run a 235 or 225. Tires are the one thing you should never be cheap about.

[Spetznaaz]

Right so i took a wheel off this morning. It wasn't very clear, but i'm pretty sure the part number is 8E0 601 025 BF which when googled comes up with 8J and ET 43. From looking at the alloy it was either ET 42 or ET 43 (apparently both exist in this design) so i'm going with ET43.

I actually went for some Goodyear UltraGrip Performance Gen 1 in 235's. Managed to get 4 with 8.5mm tread so barely used for £250 ($330), being delivered any moment. And yeah tyres are very important but i cannot afford brand new premium tyres and i wouldn't go for anything but a premium brand. I am going to get these one checked over before i put them on the car but from the looks of it they are almost brand new.

I would still like to put 245's on in the summer so i'm curious is they will fit with the 43 offset. I was thinking about putting some 19" same style ones on with 245's / 8.5J if i find a cheap set by then / if they will fit.

[EvolutionArmory]

245’s are not necessary on a 8 inch wheel. It’s silly.

Audi’s don’t have any issues with grip so all you’re doing is throwing on a heavier, more expensive tire that might rub. Then you gotta play the spacer game.

Just forget about 245 tires. There’s no need on a wheel that narrow.

Well i'd argue that, as an example, 19" alloys aren't "necessary" and could be considered "silly" but it's down to personal preferences really. As i stated, it's not about having extra grip it's that i like the aesthetic look of wider tyres (the winters was because more were available in 245).

Also this is why i was considering going for a 19" 8.5J next summer.

[EvolutionArmory]

On a 8.5 wide wheel a 245 makes a little more sense and will have an easier time fitting because it will have more stretch. On a 8 inch wheel it might fit without rubbing up in the air but as soon as you put it on the ground and actually try to turn, side wall flex can have you rubbing the upright or fender.

My snow tires are a 245 and the only reason I bought them is because they came on a good set of B8 A4 wheels, were like new and were cheap enough. I have to run spacers and rolled fenders to run them. No big deal because having rolled fenders works for me year round but I won’t be replacing them with another 245 set when they wear out, that’s for sure.

What is silly is that you would consider picking a tire that looks a certain way VS being practical and running the right tire size for the wheel.

You want some stretch if you want to run 18’s and 19’s on these cars. Plus size wheels are very dependent on offset and tire size with these cars and having a little stretch can only help you.

Does that make more sense?
